Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510134, here are decompositions:

13 + 31510121 = 31510134
23 + 31510111 = 31510134
41 + 31510093 = 31510134
43 + 31510091 = 31510134
113 + 31510021 = 31510134
127 + 31510007 = 31510134
163 + 31509971 = 31510134
167 + 31509967 = 31510134

Showing the first eight; more decompositions exist.
