Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563624, here are decompositions:

23 + 31563601 = 31563624
31 + 31563593 = 31563624
73 + 31563551 = 31563624
97 + 31563527 = 31563624
173 + 31563451 = 31563624
181 + 31563443 = 31563624
193 + 31563431 = 31563624
223 + 31563401 = 31563624

Showing the first eight; more decompositions exist.
