Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563204, here are decompositions:

11 + 31563193 = 31563204
17 + 31563187 = 31563204
41 + 31563163 = 31563204
67 + 31563137 = 31563204
73 + 31563131 = 31563204
131 + 31563073 = 31563204
163 + 31563041 = 31563204
173 + 31563031 = 31563204

Showing the first eight; more decompositions exist.
