Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603516, here are decompositions:

5 + 31603511 = 31603516
29 + 31603487 = 31603516
89 + 31603427 = 31603516
149 + 31603367 = 31603516
173 + 31603343 = 31603516
257 + 31603259 = 31603516
359 + 31603157 = 31603516
443 + 31603073 = 31603516

Showing the first eight; more decompositions exist.
