Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603736, here are decompositions:

19 + 31603717 = 31603736
79 + 31603657 = 31603736
127 + 31603609 = 31603736
487 + 31603249 = 31603736
613 + 31603123 = 31603736
709 + 31603027 = 31603736
727 + 31603009 = 31603736
859 + 31602877 = 31603736

Showing the first eight; more decompositions exist.
