Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533794, here are decompositions:

3 + 31533791 = 31533794
31 + 31533763 = 31533794
73 + 31533721 = 31533794
157 + 31533637 = 31533794
163 + 31533631 = 31533794
181 + 31533613 = 31533794
223 + 31533571 = 31533794
277 + 31533517 = 31533794

Showing the first eight; more decompositions exist.
