Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608974, here are decompositions:

3 + 31608971 = 31608974
37 + 31608937 = 31608974
151 + 31608823 = 31608974
157 + 31608817 = 31608974
181 + 31608793 = 31608974
277 + 31608697 = 31608974
307 + 31608667 = 31608974
547 + 31608427 = 31608974

Showing the first eight; more decompositions exist.
