Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563336, here are decompositions:

53 + 31563283 = 31563336
59 + 31563277 = 31563336
67 + 31563269 = 31563336
83 + 31563253 = 31563336
127 + 31563209 = 31563336
149 + 31563187 = 31563336
173 + 31563163 = 31563336
199 + 31563137 = 31563336

Showing the first eight; more decompositions exist.
