Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603224, here are decompositions:

31 + 31603193 = 31603224
67 + 31603157 = 31603224
83 + 31603141 = 31603224
101 + 31603123 = 31603224
113 + 31603111 = 31603224
151 + 31603073 = 31603224
197 + 31603027 = 31603224
251 + 31602973 = 31603224

Showing the first eight; more decompositions exist.
