Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603674, here are decompositions:

17 + 31603657 = 31603674
31 + 31603643 = 31603674
61 + 31603613 = 31603674
97 + 31603577 = 31603674
107 + 31603567 = 31603674
163 + 31603511 = 31603674
281 + 31603393 = 31603674
293 + 31603381 = 31603674

Showing the first eight; more decompositions exist.
