Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550656, here are decompositions:

29 + 31550627 = 31550656
83 + 31550573 = 31550656
113 + 31550543 = 31550656
197 + 31550459 = 31550656
317 + 31550339 = 31550656
443 + 31550213 = 31550656
479 + 31550177 = 31550656
503 + 31550153 = 31550656

Showing the first eight; more decompositions exist.
