Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560096, here are decompositions:

17 + 31560079 = 31560096
23 + 31560073 = 31560096
37 + 31560059 = 31560096
67 + 31560029 = 31560096
107 + 31559989 = 31560096
263 + 31559833 = 31560096
283 + 31559813 = 31560096
313 + 31559783 = 31560096

Showing the first eight; more decompositions exist.
