Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603374, here are decompositions:

7 + 31603367 = 31603374
13 + 31603361 = 31603374
31 + 31603343 = 31603374
113 + 31603261 = 31603374
181 + 31603193 = 31603374
227 + 31603147 = 31603374
233 + 31603141 = 31603374
251 + 31603123 = 31603374

Showing the first eight; more decompositions exist.
