Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550796, here are decompositions:

5 + 31550791 = 31550796
73 + 31550723 = 31550796
97 + 31550699 = 31550796
197 + 31550599 = 31550796
223 + 31550573 = 31550796
227 + 31550569 = 31550796
239 + 31550557 = 31550796
257 + 31550539 = 31550796

Showing the first eight; more decompositions exist.
