Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603506, here are decompositions:

17 + 31603489 = 31603506
19 + 31603487 = 31603506
79 + 31603427 = 31603506
113 + 31603393 = 31603506
139 + 31603367 = 31603506
163 + 31603343 = 31603506
197 + 31603309 = 31603506
257 + 31603249 = 31603506

Showing the first eight; more decompositions exist.
