Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603362, here are decompositions:

19 + 31603343 = 31603362
53 + 31603309 = 31603362
101 + 31603261 = 31603362
103 + 31603259 = 31603362
113 + 31603249 = 31603362
223 + 31603139 = 31603362
239 + 31603123 = 31603362
251 + 31603111 = 31603362

Showing the first eight; more decompositions exist.
