Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563410, here are decompositions:

7 + 31563403 = 31563410
19 + 31563391 = 31563410
61 + 31563349 = 31563410
127 + 31563283 = 31563410
157 + 31563253 = 31563410
223 + 31563187 = 31563410
283 + 31563127 = 31563410
337 + 31563073 = 31563410

Showing the first eight; more decompositions exist.
