Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31708, here are decompositions:

41 + 31667 = 31708
59 + 31649 = 31708
101 + 31607 = 31708
107 + 31601 = 31708
167 + 31541 = 31708
191 + 31517 = 31708
197 + 31511 = 31708
227 + 31481 = 31708

Showing the first eight; more decompositions exist.
