Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533176, here are decompositions:

43 + 31533133 = 31533176
79 + 31533097 = 31533176
163 + 31533013 = 31533176
277 + 31532899 = 31533176
313 + 31532863 = 31533176
439 + 31532737 = 31533176
523 + 31532653 = 31533176
739 + 31532437 = 31533176

Showing the first eight; more decompositions exist.
