Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31768, here are decompositions:

17 + 31751 = 31768
41 + 31727 = 31768
47 + 31721 = 31768
101 + 31667 = 31768
167 + 31601 = 31768
227 + 31541 = 31768
251 + 31517 = 31768
257 + 31511 = 31768

Showing the first eight; more decompositions exist.
