Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564336, here are decompositions:

3 + 31564333 = 31564336
5 + 31564331 = 31564336
107 + 31564229 = 31564336
173 + 31564163 = 31564336
179 + 31564157 = 31564336
197 + 31564139 = 31564336
233 + 31564103 = 31564336
257 + 31564079 = 31564336

Showing the first eight; more decompositions exist.
