Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603734, here are decompositions:

13 + 31603721 = 31603734
17 + 31603717 = 31603734
23 + 31603711 = 31603734
53 + 31603681 = 31603734
157 + 31603577 = 31603734
167 + 31603567 = 31603734
181 + 31603553 = 31603734
223 + 31603511 = 31603734

Showing the first eight; more decompositions exist.
