Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540514, here are decompositions:

13 + 31540501 = 31540514
43 + 31540471 = 31540514
73 + 31540441 = 31540514
97 + 31540417 = 31540514
151 + 31540363 = 31540514
307 + 31540207 = 31540514
367 + 31540147 = 31540514
547 + 31539967 = 31540514

Showing the first eight; more decompositions exist.
