Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533922, here are decompositions:

3 + 31533919 = 31533922
11 + 31533911 = 31533922
83 + 31533839 = 31533922
89 + 31533833 = 31533922
131 + 31533791 = 31533922
149 + 31533773 = 31533922
263 + 31533659 = 31533922
281 + 31533641 = 31533922

Showing the first eight; more decompositions exist.
