Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539982, here are decompositions:

11 + 31539971 = 31539982
269 + 31539713 = 31539982
311 + 31539671 = 31539982
389 + 31539593 = 31539982
569 + 31539413 = 31539982
653 + 31539329 = 31539982
839 + 31539143 = 31539982
1031 + 31538951 = 31539982

Showing the first eight; more decompositions exist.
