Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569826, here are decompositions:

59 + 31569767 = 31569826
89 + 31569737 = 31569826
137 + 31569689 = 31569826
179 + 31569647 = 31569826
227 + 31569599 = 31569826
257 + 31569569 = 31569826
347 + 31569479 = 31569826
389 + 31569437 = 31569826

Showing the first eight; more decompositions exist.
