Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533826, here are decompositions:

3 + 31533823 = 31533826
53 + 31533773 = 31533826
167 + 31533659 = 31533826
227 + 31533599 = 31533826
239 + 31533587 = 31533826
263 + 31533563 = 31533826
293 + 31533533 = 31533826
557 + 31533269 = 31533826

Showing the first eight; more decompositions exist.
