Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626748, here are decompositions:

59 + 31626689 = 31626748
191 + 31626557 = 31626748
311 + 31626437 = 31626748
359 + 31626389 = 31626748
389 + 31626359 = 31626748
557 + 31626191 = 31626748
617 + 31626131 = 31626748
761 + 31625987 = 31626748

Showing the first eight; more decompositions exist.
