Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563696, here are decompositions:

13 + 31563683 = 31563696
103 + 31563593 = 31563696
127 + 31563569 = 31563696
233 + 31563463 = 31563696
293 + 31563403 = 31563696
337 + 31563359 = 31563696
347 + 31563349 = 31563696
349 + 31563347 = 31563696

Showing the first eight; more decompositions exist.
