Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596646, here are decompositions:

149 + 31596497 = 31596646
173 + 31596473 = 31596646
227 + 31596419 = 31596646
233 + 31596413 = 31596646
353 + 31596293 = 31596646
503 + 31596143 = 31596646
617 + 31596029 = 31596646
677 + 31595969 = 31596646

Showing the first eight; more decompositions exist.
