Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603392, here are decompositions:

11 + 31603381 = 31603392
31 + 31603361 = 31603392
83 + 31603309 = 31603392
131 + 31603261 = 31603392
199 + 31603193 = 31603392
251 + 31603141 = 31603392
269 + 31603123 = 31603392
281 + 31603111 = 31603392

Showing the first eight; more decompositions exist.
