Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603662, here are decompositions:

5 + 31603657 = 31603662
19 + 31603643 = 31603662
53 + 31603609 = 31603662
109 + 31603553 = 31603662
151 + 31603511 = 31603662
173 + 31603489 = 31603662
269 + 31603393 = 31603662
281 + 31603381 = 31603662

Showing the first eight; more decompositions exist.
