Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507314, here are decompositions:

17 + 31507297 = 31507314
31 + 31507283 = 31507314
43 + 31507271 = 31507314
71 + 31507243 = 31507314
103 + 31507211 = 31507314
197 + 31507117 = 31507314
227 + 31507087 = 31507314
233 + 31507081 = 31507314

Showing the first eight; more decompositions exist.
