Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451596, here are decompositions:

17 + 31451579 = 31451596
47 + 31451549 = 31451596
107 + 31451489 = 31451596
563 + 31451033 = 31451596
599 + 31450997 = 31451596
647 + 31450949 = 31451596
773 + 31450823 = 31451596
809 + 31450787 = 31451596

Showing the first eight; more decompositions exist.
