2+3,11+3,3+17
Only one pair.
37 + 3
5 and 103 is one possible pair.
79 + 19 + 2
2+3,11+3,3+17
The sum of any pair of prime numbers greater than 2 is an even number.
2 and 5 are one such pair.
You can't write that as the sum of two prime numbers. Note: Goldbach's Conjecture (for expressing numbers as the sum of two prime numbers) applies to EVEN numbers.
11 and 5 13 and 3
Only one pair.
37 + 3
5 and 103 is one possible pair.
Since there is an infinite set of prime numbers the answer would be infinity.
2 + 23 = 25
79 + 19 + 2
It is simply: 3+23 = 26 because 3 and 23 are prime numbers
