Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540508, here are decompositions:

7 + 31540501 = 31540508
19 + 31540489 = 31540508
37 + 31540471 = 31540508
67 + 31540441 = 31540508
199 + 31540309 = 31540508
211 + 31540297 = 31540508
409 + 31540099 = 31540508
499 + 31540009 = 31540508

Showing the first eight; more decompositions exist.
