Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626862, here are decompositions:

5 + 31626857 = 31626862
23 + 31626839 = 31626862
173 + 31626689 = 31626862
401 + 31626461 = 31626862
479 + 31626383 = 31626862
503 + 31626359 = 31626862
653 + 31626209 = 31626862
809 + 31626053 = 31626862

Showing the first eight; more decompositions exist.
