Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608942, here are decompositions:

5 + 31608937 = 31608942
31 + 31608911 = 31608942
59 + 31608883 = 31608942
89 + 31608853 = 31608942
149 + 31608793 = 31608942
163 + 31608779 = 31608942
193 + 31608749 = 31608942
229 + 31608713 = 31608942

Showing the first eight; more decompositions exist.
