Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603410, here are decompositions:

17 + 31603393 = 31603410
29 + 31603381 = 31603410
43 + 31603367 = 31603410
67 + 31603343 = 31603410
101 + 31603309 = 31603410
149 + 31603261 = 31603410
151 + 31603259 = 31603410
263 + 31603147 = 31603410

Showing the first eight; more decompositions exist.
