Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510264, here are decompositions:

41 + 31510223 = 31510264
47 + 31510217 = 31510264
131 + 31510133 = 31510264
173 + 31510091 = 31510264
257 + 31510007 = 31510264
263 + 31510001 = 31510264
293 + 31509971 = 31510264
491 + 31509773 = 31510264

Showing the first eight; more decompositions exist.
