Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563552, here are decompositions:

61 + 31563491 = 31563552
89 + 31563463 = 31563552
101 + 31563451 = 31563552
109 + 31563443 = 31563552
149 + 31563403 = 31563552
151 + 31563401 = 31563552
193 + 31563359 = 31563552
269 + 31563283 = 31563552

Showing the first eight; more decompositions exist.
