Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569336, here are decompositions:

17 + 31569319 = 31569336
59 + 31569277 = 31569336
79 + 31569257 = 31569336
89 + 31569247 = 31569336
103 + 31569233 = 31569336
107 + 31569229 = 31569336
167 + 31569169 = 31569336
179 + 31569157 = 31569336

Showing the first eight; more decompositions exist.
