Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563492, here are decompositions:

29 + 31563463 = 31563492
41 + 31563451 = 31563492
61 + 31563431 = 31563492
89 + 31563403 = 31563492
101 + 31563391 = 31563492
223 + 31563269 = 31563492
239 + 31563253 = 31563492
271 + 31563221 = 31563492

Showing the first eight; more decompositions exist.
