Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563494, here are decompositions:

3 + 31563491 = 31563494
31 + 31563463 = 31563494
43 + 31563451 = 31563494
103 + 31563391 = 31563494
211 + 31563283 = 31563494
241 + 31563253 = 31563494
307 + 31563187 = 31563494
331 + 31563163 = 31563494

Showing the first eight; more decompositions exist.
