Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566328, here are decompositions:

11 + 31566317 = 31566328
29 + 31566299 = 31566328
41 + 31566287 = 31566328
107 + 31566221 = 31566328
137 + 31566191 = 31566328
191 + 31566137 = 31566328
197 + 31566131 = 31566328
251 + 31566077 = 31566328

Showing the first eight; more decompositions exist.
