Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550296, here are decompositions:

83 + 31550213 = 31550296
233 + 31550063 = 31550296
269 + 31550027 = 31550296
317 + 31549979 = 31550296
467 + 31549829 = 31550296
563 + 31549733 = 31550296
647 + 31549649 = 31550296
797 + 31549499 = 31550296

Showing the first eight; more decompositions exist.
