Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563692, here are decompositions:

229 + 31563463 = 31563692
241 + 31563451 = 31563692
409 + 31563283 = 31563692
439 + 31563253 = 31563692
499 + 31563193 = 31563692
619 + 31563073 = 31563692
661 + 31563031 = 31563692
691 + 31563001 = 31563692

Showing the first eight; more decompositions exist.
