Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596344, here are decompositions:

37 + 31596307 = 31596344
151 + 31596193 = 31596344
181 + 31596163 = 31596344
193 + 31596151 = 31596344
223 + 31596121 = 31596344
277 + 31596067 = 31596344
337 + 31596007 = 31596344
463 + 31595881 = 31596344

Showing the first eight; more decompositions exist.
