Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569964, here are decompositions:

11 + 31569953 = 31569964
113 + 31569851 = 31569964
197 + 31569767 = 31569964
227 + 31569737 = 31569964
263 + 31569701 = 31569964
317 + 31569647 = 31569964
347 + 31569617 = 31569964
383 + 31569581 = 31569964

Showing the first eight; more decompositions exist.
