Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550434, here are decompositions:

107 + 31550327 = 31550434
233 + 31550201 = 31550434
257 + 31550177 = 31550434
281 + 31550153 = 31550434
467 + 31549967 = 31550434
653 + 31549781 = 31550434
683 + 31549751 = 31550434
701 + 31549733 = 31550434

Showing the first eight; more decompositions exist.
