Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626074, here are decompositions:

157 + 31625917 = 31626074
163 + 31625911 = 31626074
307 + 31625767 = 31626074
313 + 31625761 = 31626074
421 + 31625653 = 31626074
457 + 31625617 = 31626074
607 + 31625467 = 31626074
643 + 31625431 = 31626074

Showing the first eight; more decompositions exist.
