Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560966, here are decompositions:

23 + 31560943 = 31560966
79 + 31560887 = 31560966
97 + 31560869 = 31560966
103 + 31560863 = 31560966
167 + 31560799 = 31560966
257 + 31560709 = 31560966
263 + 31560703 = 31560966
277 + 31560689 = 31560966

Showing the first eight; more decompositions exist.
