Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603934, here are decompositions:

3 + 31603931 = 31603934
223 + 31603711 = 31603934
277 + 31603657 = 31603934
367 + 31603567 = 31603934
541 + 31603393 = 31603934
673 + 31603261 = 31603934
787 + 31603147 = 31603934
811 + 31603123 = 31603934

Showing the first eight; more decompositions exist.
