Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539056, here are decompositions:

13 + 31539043 = 31539056
229 + 31538827 = 31539056
277 + 31538779 = 31539056
313 + 31538743 = 31539056
337 + 31538719 = 31539056
433 + 31538623 = 31539056
487 + 31538569 = 31539056
499 + 31538557 = 31539056

Showing the first eight; more decompositions exist.
