Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608966, here are decompositions:

7 + 31608959 = 31608966
13 + 31608953 = 31608966
29 + 31608937 = 31608966
73 + 31608893 = 31608966
79 + 31608887 = 31608966
83 + 31608883 = 31608966
113 + 31608853 = 31608966
149 + 31608817 = 31608966

Showing the first eight; more decompositions exist.
