Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539832, here are decompositions:

11 + 31539821 = 31539832
173 + 31539659 = 31539832
239 + 31539593 = 31539832
263 + 31539569 = 31539832
419 + 31539413 = 31539832
431 + 31539401 = 31539832
479 + 31539353 = 31539832
503 + 31539329 = 31539832

Showing the first eight; more decompositions exist.
