Absolutely, #[0] We can speed up the execution using goroutines to parallelize the prime number generation. Here's an optimized version of the code:

```go

package main

import (

"fmt"

"sync"

)

func isPrime(n int) bool {

if n <= 1 {

return false

}

for i := 2; i*i <= n; i++ {

if n%i == 0 {

return false

}

}

return true

}

func generatePrimes(start, end int, wg *sync.WaitGroup, primeChannel chan<- int) {

defer wg.Done()

for number := start; number <= end; number++ {

if isPrime(number) {

primeChannel <- number

}

}

}

func main() {

count := 0

fmt.Println("The first 100,000 prime numbers are:")

primeChannel := make(chan int)

wg := sync.WaitGroup{}

wg.Add(10)

for routineNum := 0; routineNum < 10; routineNum++ {

go generatePrimes(routineNum*10000+1,(routineNum+1)*10000,&wg ,primeChannel)

}

go func() {

wg.Wait()
