Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626038, here are decompositions:

19 + 31626019 = 31626038
127 + 31625911 = 31626038
271 + 31625767 = 31626038
277 + 31625761 = 31626038
307 + 31625731 = 31626038
421 + 31625617 = 31626038
439 + 31625599 = 31626038
571 + 31625467 = 31626038

Showing the first eight; more decompositions exist.
