Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608252, here are decompositions:

83 + 31608169 = 31608252
89 + 31608163 = 31608252
103 + 31608149 = 31608252
191 + 31608061 = 31608252
211 + 31608041 = 31608252
223 + 31608029 = 31608252
239 + 31608013 = 31608252
281 + 31607971 = 31608252

Showing the first eight; more decompositions exist.
