Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603904, here are decompositions:

61 + 31603843 = 31603904
103 + 31603801 = 31603904
193 + 31603711 = 31603904
223 + 31603681 = 31603904
337 + 31603567 = 31603904
523 + 31603381 = 31603904
643 + 31603261 = 31603904
757 + 31603147 = 31603904

Showing the first eight; more decompositions exist.
