Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603412, here are decompositions:

19 + 31603393 = 31603412
31 + 31603381 = 31603412
103 + 31603309 = 31603412
151 + 31603261 = 31603412
163 + 31603249 = 31603412
271 + 31603141 = 31603412
439 + 31602973 = 31603412
619 + 31602793 = 31603412

Showing the first eight; more decompositions exist.
