Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17656, here are decompositions:

29 + 17627 = 17656
47 + 17609 = 17656
59 + 17597 = 17656
83 + 17573 = 17656
137 + 17519 = 17656
167 + 17489 = 17656
173 + 17483 = 17656
179 + 17477 = 17656

Showing the first eight; more decompositions exist.
