Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626536, here are decompositions:

3 + 31626533 = 31626536
37 + 31626499 = 31626536
43 + 31626493 = 31626536
199 + 31626337 = 31626536
307 + 31626229 = 31626536
457 + 31626079 = 31626536
463 + 31626073 = 31626536
619 + 31625917 = 31626536

Showing the first eight; more decompositions exist.
