Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626662, here are decompositions:

43 + 31626619 = 31626662
73 + 31626589 = 31626662
163 + 31626499 = 31626662
181 + 31626481 = 31626662
241 + 31626421 = 31626662
433 + 31626229 = 31626662
643 + 31626019 = 31626662
709 + 31625953 = 31626662

Showing the first eight; more decompositions exist.
