Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566424, here are decompositions:

41 + 31566383 = 31566424
47 + 31566377 = 31566424
107 + 31566317 = 31566424
137 + 31566287 = 31566424
173 + 31566251 = 31566424
233 + 31566191 = 31566424
257 + 31566167 = 31566424
293 + 31566131 = 31566424

Showing the first eight; more decompositions exist.
