Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608956, here are decompositions:

3 + 31608953 = 31608956
19 + 31608937 = 31608956
73 + 31608883 = 31608956
103 + 31608853 = 31608956
139 + 31608817 = 31608956
163 + 31608793 = 31608956
199 + 31608757 = 31608956
229 + 31608727 = 31608956

Showing the first eight; more decompositions exist.
