Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599764, here are decompositions:

3 + 31599761 = 31599764
37 + 31599727 = 31599764
61 + 31599703 = 31599764
211 + 31599553 = 31599764
277 + 31599487 = 31599764
457 + 31599307 = 31599764
571 + 31599193 = 31599764
607 + 31599157 = 31599764

Showing the first eight; more decompositions exist.
