Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626950, here are decompositions:

7 + 31626943 = 31626950
67 + 31626883 = 31626950
109 + 31626841 = 31626950
163 + 31626787 = 31626950
241 + 31626709 = 31626950
283 + 31626667 = 31626950
331 + 31626619 = 31626950
379 + 31626571 = 31626950

Showing the first eight; more decompositions exist.
