Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608212, here are decompositions:

43 + 31608169 = 31608212
79 + 31608133 = 31608212
151 + 31608061 = 31608212
199 + 31608013 = 31608212
241 + 31607971 = 31608212
373 + 31607839 = 31608212
421 + 31607791 = 31608212
523 + 31607689 = 31608212

Showing the first eight; more decompositions exist.
