137 and 11 are two prime numbers that add up to 148.
The two prime numbers that add up to 247 are 241 and 6. 241 is a prime number because it has only two factors: 1 and 241. However, 6 is not a prime number because it has more than two factors: 1, 2, 3, and 6. When you add 241 and 6 together, you get 247.
The sum of two prime numbers will be composite unless one of the prime numbers is 2.
yes
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.
137 and 11 are two prime numbers that add up to 148.
You can not add two positive prime numbers and get zero.
23 and 19 are both prime numbers and they add up to 42.
The sum of two prime numbers will be composite unless one of the prime numbers is 2.
yes
29
443 and 3
97 and 1, of course!
31 and 5
2 and 17
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.
