Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569760, here are decompositions:

23 + 31569737 = 31569760
59 + 31569701 = 31569760
71 + 31569689 = 31569760
113 + 31569647 = 31569760
179 + 31569581 = 31569760
191 + 31569569 = 31569760
269 + 31569491 = 31569760
281 + 31569479 = 31569760

Showing the first eight; more decompositions exist.
