Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603460, here are decompositions:

67 + 31603393 = 31603460
79 + 31603381 = 31603460
151 + 31603309 = 31603460
199 + 31603261 = 31603460
211 + 31603249 = 31603460
313 + 31603147 = 31603460
337 + 31603123 = 31603460
349 + 31603111 = 31603460

Showing the first eight; more decompositions exist.
