Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533914, here are decompositions:

3 + 31533911 = 31533914
43 + 31533871 = 31533914
67 + 31533847 = 31533914
151 + 31533763 = 31533914
193 + 31533721 = 31533914
277 + 31533637 = 31533914
283 + 31533631 = 31533914
367 + 31533547 = 31533914

Showing the first eight; more decompositions exist.
