Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510396, here are decompositions:

173 + 31510223 = 31510396
179 + 31510217 = 31510396
227 + 31510169 = 31510396
257 + 31510139 = 31510396
263 + 31510133 = 31510396
317 + 31510079 = 31510396
389 + 31510007 = 31510396
503 + 31509893 = 31510396

Showing the first eight; more decompositions exist.
