Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613426, here are decompositions:

43 + 31613383 = 31613426
199 + 31613227 = 31613426
283 + 31613143 = 31613426
307 + 31613119 = 31613426
373 + 31613053 = 31613426
457 + 31612969 = 31613426
487 + 31612939 = 31613426
673 + 31612753 = 31613426

Showing the first eight; more decompositions exist.
