Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533182, here are decompositions:

181 + 31533001 = 31533182
211 + 31532971 = 31533182
223 + 31532959 = 31533182
283 + 31532899 = 31533182
349 + 31532833 = 31533182
433 + 31532749 = 31533182
523 + 31532659 = 31533182
601 + 31532581 = 31533182

Showing the first eight; more decompositions exist.
