Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514518, here are decompositions:

5 + 31514513 = 31514518
41 + 31514477 = 31514518
89 + 31514429 = 31514518
227 + 31514291 = 31514518
251 + 31514267 = 31514518
257 + 31514261 = 31514518
359 + 31514159 = 31514518
641 + 31513877 = 31514518

Showing the first eight; more decompositions exist.
