Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603566, here are decompositions:

13 + 31603553 = 31603566
47 + 31603519 = 31603566
79 + 31603487 = 31603566
139 + 31603427 = 31603566
173 + 31603393 = 31603566
199 + 31603367 = 31603566
223 + 31603343 = 31603566
257 + 31603309 = 31603566

Showing the first eight; more decompositions exist.
