Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560950, here are decompositions:

7 + 31560943 = 31560950
79 + 31560871 = 31560950
103 + 31560847 = 31560950
151 + 31560799 = 31560950
193 + 31560757 = 31560950
199 + 31560751 = 31560950
241 + 31560709 = 31560950
271 + 31560679 = 31560950

Showing the first eight; more decompositions exist.
