Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599560, here are decompositions:

7 + 31599553 = 31599560
61 + 31599499 = 31599560
73 + 31599487 = 31599560
211 + 31599349 = 31599560
313 + 31599247 = 31599560
367 + 31599193 = 31599560
457 + 31599103 = 31599560
571 + 31598989 = 31599560

Showing the first eight; more decompositions exist.
