Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450736, here are decompositions:

13 + 31450723 = 31450736
157 + 31450579 = 31450736
193 + 31450543 = 31450736
307 + 31450429 = 31450736
313 + 31450423 = 31450736
349 + 31450387 = 31450736
367 + 31450369 = 31450736
619 + 31450117 = 31450736

Showing the first eight; more decompositions exist.
