Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603134, here are decompositions:

11 + 31603123 = 31603134
23 + 31603111 = 31603134
61 + 31603073 = 31603134
107 + 31603027 = 31603134
257 + 31602877 = 31603134
271 + 31602863 = 31603134
281 + 31602853 = 31603134
331 + 31602803 = 31603134

Showing the first eight; more decompositions exist.
