Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627010, here are decompositions:

3 + 31627007 = 31627010
31 + 31626979 = 31627010
43 + 31626967 = 31627010
67 + 31626943 = 31627010
127 + 31626883 = 31627010
223 + 31626787 = 31627010
421 + 31626589 = 31627010
439 + 31626571 = 31627010

Showing the first eight; more decompositions exist.
