Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539682, here are decompositions:

11 + 31539671 = 31539682
23 + 31539659 = 31539682
89 + 31539593 = 31539682
113 + 31539569 = 31539682
269 + 31539413 = 31539682
281 + 31539401 = 31539682
353 + 31539329 = 31539682
491 + 31539191 = 31539682

Showing the first eight; more decompositions exist.
