Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608896, here are decompositions:

3 + 31608893 = 31608896
13 + 31608883 = 31608896
43 + 31608853 = 31608896
73 + 31608823 = 31608896
79 + 31608817 = 31608896
103 + 31608793 = 31608896
139 + 31608757 = 31608896
199 + 31608697 = 31608896

Showing the first eight; more decompositions exist.
