Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626960, here are decompositions:

17 + 31626943 = 31626960
61 + 31626899 = 31626960
67 + 31626893 = 31626960
103 + 31626857 = 31626960
163 + 31626797 = 31626960
173 + 31626787 = 31626960
193 + 31626767 = 31626960
251 + 31626709 = 31626960

Showing the first eight; more decompositions exist.
