Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569764, here are decompositions:

3 + 31569761 = 31569764
13 + 31569751 = 31569764
73 + 31569691 = 31569764
151 + 31569613 = 31569764
283 + 31569481 = 31569764
397 + 31569367 = 31569764
463 + 31569301 = 31569764
487 + 31569277 = 31569764

Showing the first eight; more decompositions exist.
