Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603760, here are decompositions:

3 + 31603757 = 31603760
43 + 31603717 = 31603760
79 + 31603681 = 31603760
103 + 31603657 = 31603760
151 + 31603609 = 31603760
193 + 31603567 = 31603760
241 + 31603519 = 31603760
271 + 31603489 = 31603760

Showing the first eight; more decompositions exist.
