Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626338, here are decompositions:

109 + 31626229 = 31626338
229 + 31626109 = 31626338
421 + 31625917 = 31626338
571 + 31625767 = 31626338
577 + 31625761 = 31626338
607 + 31625731 = 31626338
691 + 31625647 = 31626338
739 + 31625599 = 31626338

Showing the first eight; more decompositions exist.
