Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603892, here are decompositions:

3 + 31603889 = 31603892
13 + 31603879 = 31603892
181 + 31603711 = 31603892
211 + 31603681 = 31603892
283 + 31603609 = 31603892
373 + 31603519 = 31603892
499 + 31603393 = 31603892
631 + 31603261 = 31603892

Showing the first eight; more decompositions exist.
