Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607314, here are decompositions:

5 + 31607309 = 31607314
17 + 31607297 = 31607314
23 + 31607291 = 31607314
107 + 31607207 = 31607314
113 + 31607201 = 31607314
227 + 31607087 = 31607314
317 + 31606997 = 31607314
383 + 31606931 = 31607314

Showing the first eight; more decompositions exist.
