Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533386, here are decompositions:

7 + 31533379 = 31533386
43 + 31533343 = 31533386
127 + 31533259 = 31533386
373 + 31533013 = 31533386
463 + 31532923 = 31533386
487 + 31532899 = 31533386
523 + 31532863 = 31533386
727 + 31532659 = 31533386

Showing the first eight; more decompositions exist.
