Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603836, here are decompositions:

7 + 31603829 = 31603836
79 + 31603757 = 31603836
97 + 31603739 = 31603836
127 + 31603709 = 31603836
179 + 31603657 = 31603836
193 + 31603643 = 31603836
223 + 31603613 = 31603836
227 + 31603609 = 31603836

Showing the first eight; more decompositions exist.
