The `math/big` package in Go supports arbitrary-precision arithmetic with big integers. The package also provides several functions for prime number operations, such as `ProbablyPrime`.

The `ProbablyPrime` function returns true if the given number is probably prime, and false if it is definitely composite. The function takes two arguments, the first being the number to be tested for primality, and the second is the number of iterations for the Miller-Rabin test.

Here are some examples:

**Example 1:**

In this example, `ProbablyPrime` is used to test if the number 123456789 is a prime number. Since we have used 10 iterations for the Miller-Rabin test, the function will run 10 tests and return true if the number passes all the tests.

**Example 2:**

The `ProbablyPrime` function returns true if the given number is probably prime, and false if it is definitely composite. The function takes two arguments, the first being the number to be tested for primality, and the second is the number of iterations for the Miller-Rabin test.

Here are some examples:

import "math/big" func main() { num := big.NewInt(123456789) if num.ProbablyPrime(10) { fmt.Println("The number is probably prime") } else { fmt.Println("The number is definitely composite") } }

In this example, `ProbablyPrime` is used to test if the number 123456789 is a prime number. Since we have used 10 iterations for the Miller-Rabin test, the function will run 10 tests and return true if the number passes all the tests.

import "math/big" func main() { num := big.NewInt(999999999999) if num.ProbablyPrime(5) { fmt.Println("The number is probably prime") } else { fmt.Println("The number is definitely composite") } }In this example, `ProbablyPrime` is used to test if the number 999999999999 is a prime number. However, this time we have used only 5 iterations for the Miller-Rabin test, meaning that the function will run only 5 tests and return false if the number fails any of the tests. Therefore, the `math/big` package in Go provides support for various mathematical operations involving big integers, including functions for prime number operations like `ProbablyPrime`.
