Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603698, here are decompositions:

17 + 31603681 = 31603698
41 + 31603657 = 31603698
89 + 31603609 = 31603698
131 + 31603567 = 31603698
179 + 31603519 = 31603698
211 + 31603487 = 31603698
271 + 31603427 = 31603698
317 + 31603381 = 31603698

Showing the first eight; more decompositions exist.
