Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560982, here are decompositions:

3 + 31560979 = 31560982
41 + 31560941 = 31560982
71 + 31560911 = 31560982
113 + 31560869 = 31560982
191 + 31560791 = 31560982
251 + 31560731 = 31560982
263 + 31560719 = 31560982
269 + 31560713 = 31560982

Showing the first eight; more decompositions exist.
