Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603684, here are decompositions:

3 + 31603681 = 31603684
41 + 31603643 = 31603684
71 + 31603613 = 31603684
107 + 31603577 = 31603684
131 + 31603553 = 31603684
173 + 31603511 = 31603684
197 + 31603487 = 31603684
257 + 31603427 = 31603684

Showing the first eight; more decompositions exist.
