Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626836, here are decompositions:

127 + 31626709 = 31626836
229 + 31626607 = 31626836
337 + 31626499 = 31626836
499 + 31626337 = 31626836
607 + 31626229 = 31626836
643 + 31626193 = 31626836
727 + 31626109 = 31626836
757 + 31626079 = 31626836

Showing the first eight; more decompositions exist.
