Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626612, here are decompositions:

5 + 31626607 = 31626612
23 + 31626589 = 31626612
41 + 31626571 = 31626612
79 + 31626533 = 31626612
113 + 31626499 = 31626612
131 + 31626481 = 31626612
151 + 31626461 = 31626612
191 + 31626421 = 31626612

Showing the first eight; more decompositions exist.
