Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569652, here are decompositions:

5 + 31569647 = 31569652
11 + 31569641 = 31569652
53 + 31569599 = 31569652
71 + 31569581 = 31569652
83 + 31569569 = 31569652
173 + 31569479 = 31569652
293 + 31569359 = 31569652
419 + 31569233 = 31569652

Showing the first eight; more decompositions exist.
