Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603766, here are decompositions:

109 + 31603657 = 31603766
157 + 31603609 = 31603766
199 + 31603567 = 31603766
277 + 31603489 = 31603766
373 + 31603393 = 31603766
457 + 31603309 = 31603766
619 + 31603147 = 31603766
643 + 31603123 = 31603766

Showing the first eight; more decompositions exist.
