Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456336, here are decompositions:

5 + 31456331 = 31456336
17 + 31456319 = 31456336
59 + 31456277 = 31456336
89 + 31456247 = 31456336
137 + 31456199 = 31456336
173 + 31456163 = 31456336
257 + 31456079 = 31456336
269 + 31456067 = 31456336

Showing the first eight; more decompositions exist.
