Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533814, here are decompositions:

23 + 31533791 = 31533814
41 + 31533773 = 31533814
107 + 31533707 = 31533814
173 + 31533641 = 31533814
227 + 31533587 = 31533814
233 + 31533581 = 31533814
251 + 31533563 = 31533814
281 + 31533533 = 31533814

Showing the first eight; more decompositions exist.
