Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564114, here are decompositions:

11 + 31564103 = 31564114
167 + 31563947 = 31564114
173 + 31563941 = 31564114
233 + 31563881 = 31564114
251 + 31563863 = 31564114
431 + 31563683 = 31564114
443 + 31563671 = 31564114
467 + 31563647 = 31564114

Showing the first eight; more decompositions exist.
