Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533296, here are decompositions:

37 + 31533259 = 31533296
163 + 31533133 = 31533296
199 + 31533097 = 31533296
283 + 31533013 = 31533296
337 + 31532959 = 31533296
373 + 31532923 = 31533296
397 + 31532899 = 31533296
433 + 31532863 = 31533296

Showing the first eight; more decompositions exist.
