Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463656, here are decompositions:

137 + 31463519 = 31463656
149 + 31463507 = 31463656
167 + 31463489 = 31463656
173 + 31463483 = 31463656
179 + 31463477 = 31463656
197 + 31463459 = 31463656
227 + 31463429 = 31463656
269 + 31463387 = 31463656

Showing the first eight; more decompositions exist.
