Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552960, here are decompositions:

17 + 31552943 = 31552960
41 + 31552919 = 31552960
53 + 31552907 = 31552960
107 + 31552853 = 31552960
113 + 31552847 = 31552960
227 + 31552733 = 31552960
233 + 31552727 = 31552960
239 + 31552721 = 31552960

Showing the first eight; more decompositions exist.
