Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540616, here are decompositions:

43 + 31540573 = 31540616
127 + 31540489 = 31540616
199 + 31540417 = 31540616
277 + 31540339 = 31540616
307 + 31540309 = 31540616
409 + 31540207 = 31540616
607 + 31540009 = 31540616
727 + 31539889 = 31540616

Showing the first eight; more decompositions exist.
