Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563636, here are decompositions:

43 + 31563593 = 31563636
67 + 31563569 = 31563636
109 + 31563527 = 31563636
173 + 31563463 = 31563636
193 + 31563443 = 31563636
233 + 31563403 = 31563636
277 + 31563359 = 31563636
353 + 31563283 = 31563636

Showing the first eight; more decompositions exist.
