Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603344, here are decompositions:

83 + 31603261 = 31603344
151 + 31603193 = 31603344
197 + 31603147 = 31603344
233 + 31603111 = 31603344
271 + 31603073 = 31603344
317 + 31603027 = 31603344
467 + 31602877 = 31603344
491 + 31602853 = 31603344

Showing the first eight; more decompositions exist.
