func main() {
limit := int(math.Log(1e7) * 1e7 * 1.2) // should be more than enough
primes := rcu.Primes(limit)
fmt.Println("The first 20 pairs of natural numbers whose sum is prime are:")

}
fmt.Println("\nThe 10 millionth such pair is:")
p := primes[1e7]
fmt.Printf("%2d + %2d = %2d\n", hp, hp+1, p)

Line 493 ⟶ 498:
35 + 36 = 71
36 + 37 = 73
The 10 millionth such pair is:
89712345 + 89712346 = 179424691
