Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533832, here are decompositions:

3 + 31533829 = 31533832
41 + 31533791 = 31533832
59 + 31533773 = 31533832
173 + 31533659 = 31533832
191 + 31533641 = 31533832
233 + 31533599 = 31533832
251 + 31533581 = 31533832
269 + 31533563 = 31533832

Showing the first eight; more decompositions exist.
