Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510266, here are decompositions:

23 + 31510243 = 31510266
43 + 31510223 = 31510266
79 + 31510187 = 31510266
97 + 31510169 = 31510266
127 + 31510139 = 31510266
173 + 31510093 = 31510266
257 + 31510009 = 31510266
317 + 31509949 = 31510266

Showing the first eight; more decompositions exist.
