Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563634, here are decompositions:

41 + 31563593 = 31563634
83 + 31563551 = 31563634
107 + 31563527 = 31563634
191 + 31563443 = 31563634
233 + 31563401 = 31563634
257 + 31563377 = 31563634
503 + 31563131 = 31563634
593 + 31563041 = 31563634

Showing the first eight; more decompositions exist.
