Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569676, here are decompositions:

29 + 31569647 = 31569676
59 + 31569617 = 31569676
107 + 31569569 = 31569676
197 + 31569479 = 31569676
227 + 31569449 = 31569676
239 + 31569437 = 31569676
317 + 31569359 = 31569676
389 + 31569287 = 31569676

Showing the first eight; more decompositions exist.
