Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595456, here are decompositions:

73 + 31595383 = 31595456
283 + 31595173 = 31595456
397 + 31595059 = 31595456
457 + 31594999 = 31595456
643 + 31594813 = 31595456
709 + 31594747 = 31595456
727 + 31594729 = 31595456
757 + 31594699 = 31595456

Showing the first eight; more decompositions exist.
