Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31744, here are decompositions:

3 + 31741 = 31744
17 + 31727 = 31744
23 + 31721 = 31744
101 + 31643 = 31744
137 + 31607 = 31744
197 + 31547 = 31744
227 + 31517 = 31744
233 + 31511 = 31744

Showing the first eight; more decompositions exist.
