Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566336, here are decompositions:

7 + 31566329 = 31566336
19 + 31566317 = 31566336
37 + 31566299 = 31566336
47 + 31566289 = 31566336
89 + 31566247 = 31566336
167 + 31566169 = 31566336
199 + 31566137 = 31566336
257 + 31566079 = 31566336

Showing the first eight; more decompositions exist.
