Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603494, here are decompositions:

5 + 31603489 = 31603494
7 + 31603487 = 31603494
67 + 31603427 = 31603494
101 + 31603393 = 31603494
113 + 31603381 = 31603494
127 + 31603367 = 31603494
151 + 31603343 = 31603494
233 + 31603261 = 31603494

Showing the first eight; more decompositions exist.
