Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626966, here are decompositions:

23 + 31626943 = 31626966
67 + 31626899 = 31626966
73 + 31626893 = 31626966
83 + 31626883 = 31626966
97 + 31626869 = 31626966
109 + 31626857 = 31626966
127 + 31626839 = 31626966
139 + 31626827 = 31626966

Showing the first eight; more decompositions exist.
