Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563414, here are decompositions:

11 + 31563403 = 31563414
13 + 31563401 = 31563414
23 + 31563391 = 31563414
37 + 31563377 = 31563414
67 + 31563347 = 31563414
131 + 31563283 = 31563414
137 + 31563277 = 31563414
193 + 31563221 = 31563414

Showing the first eight; more decompositions exist.
