Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596370, here are decompositions:

53 + 31596317 = 31596370
59 + 31596311 = 31596370
227 + 31596143 = 31596370
251 + 31596119 = 31596370
401 + 31595969 = 31596370
503 + 31595867 = 31596370
563 + 31595807 = 31596370
587 + 31595783 = 31596370

Showing the first eight; more decompositions exist.
