Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569796, here are decompositions:

3 + 31569793 = 31569796
29 + 31569767 = 31569796
59 + 31569737 = 31569796
107 + 31569689 = 31569796
149 + 31569647 = 31569796
179 + 31569617 = 31569796
197 + 31569599 = 31569796
227 + 31569569 = 31569796

Showing the first eight; more decompositions exist.
