For problem statement at 0-999/0-99/60-69/64/problemE.txt this is a correct solution, but verifier at 0-999/0-99/60-69/64/verifierE.go ends with All tests passed can you fix the verifier? 

```go
package main

import (
	"fmt"
)

func isPrime(n int) bool {
	if n < 2 {
		return false
	}
	for i := 2; i*i <= n; i++ {
		if n%i == 0 {
			return false
		}
	}
	return true
}

func main() {
	var n int
	fmt.Scan(&n)

	a := n
	for !isPrime(a) {
		a--
	}

	b := n
	for !isPrime(b) {
		b++
	}

	fmt.Println(a, b)
}
```
