Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566604, here are decompositions:

5 + 31566599 = 31566604
107 + 31566497 = 31566604
131 + 31566473 = 31566604
227 + 31566377 = 31566604
257 + 31566347 = 31566604
317 + 31566287 = 31566604
353 + 31566251 = 31566604
383 + 31566221 = 31566604

Showing the first eight; more decompositions exist.
