Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533392, here are decompositions:

3 + 31533389 = 31533392
13 + 31533379 = 31533392
379 + 31533013 = 31533392
421 + 31532971 = 31533392
433 + 31532959 = 31533392
643 + 31532749 = 31533392
733 + 31532659 = 31533392
739 + 31532653 = 31533392

Showing the first eight; more decompositions exist.
