If you're talking about which two prime numbers added together equals to 19, then the answer is 2 and 17. They are both prime numbers, and they add up to be 19.
23 and 19 are both prime numbers and they add up to 42.
43 and 19
19+2 are two prime numbers that add up to 21
None of this works. There aren't two prime numbers that multiply to 75 and the only two that add to it are 73 and 2. There aren't two prime numbers whose difference is 19. Two numbers that satisfy those conditions are 47 and 28, but 28 isn't prime.
How about the prime numbers of: 47+19 = 66
19 and 19
5 + 19 7 + 17 11 + 13
They are 2 and 17 = 19 which is also a prime number
19 and 5 are prime numbers and 19+5 = 24
The two prime numbers immediately following 17 are 19 and 23.
Oh, dude, prime numbers are like those special numbers that only have two factors, 1 and themselves, right? So, like, 25 is not a prime number because it has more factors. But if you wanna know two prime numbers that add up to 25, you'd have to go with 13 and 12. Wait, no, scratch that, 13 and 12 are not prime. Whoops! I meant 13 and 2!
