Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451096, here are decompositions:

67 + 31451029 = 31451096
199 + 31450897 = 31451096
307 + 31450789 = 31451096
373 + 31450723 = 31451096
613 + 31450483 = 31451096
673 + 31450423 = 31451096
709 + 31450387 = 31451096
727 + 31450369 = 31451096

Showing the first eight; more decompositions exist.
