Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624, here are decompositions:

17 + 31607 = 31624
23 + 31601 = 31624
41 + 31583 = 31624
83 + 31541 = 31624
107 + 31517 = 31624
113 + 31511 = 31624
227 + 31397 = 31624
233 + 31391 = 31624

Showing the first eight; more decompositions exist.
