There are two pairs of prime numbers that express 18 as the sum of two prime numbers: 7 + 11 = 18 and 5 + 13 = 18.
There are 3 pairs of prime numbers with sum of 36. These are: (31, 5), (29, 7), (23, 13), & (19, 17) Hope this helps! :D

There are three pairs.
2 and 5 are one such pair.
I assume you are asking the question "what two prime numbers sum to 44". There may be other pairs of prime numbers that sum to 44, but 37 and 7 are both primes and their sum = 44.
They are 2 and 29
