Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533056, here are decompositions:

43 + 31533013 = 31533056
97 + 31532959 = 31533056
157 + 31532899 = 31533056
193 + 31532863 = 31533056
223 + 31532833 = 31533056
307 + 31532749 = 31533056
397 + 31532659 = 31533056
463 + 31532593 = 31533056

Showing the first eight; more decompositions exist.
