Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552966, here are decompositions:

23 + 31552943 = 31552966
47 + 31552919 = 31552966
59 + 31552907 = 31552966
83 + 31552883 = 31552966
113 + 31552853 = 31552966
149 + 31552817 = 31552966
233 + 31552733 = 31552966
239 + 31552727 = 31552966

Showing the first eight; more decompositions exist.
