Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603512, here are decompositions:

23 + 31603489 = 31603512
131 + 31603381 = 31603512
151 + 31603361 = 31603512
251 + 31603261 = 31603512
263 + 31603249 = 31603512
373 + 31603139 = 31603512
389 + 31603123 = 31603512
401 + 31603111 = 31603512

Showing the first eight; more decompositions exist.
