Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557220, here are decompositions:

17 + 33557203 = 33557220
23 + 33557197 = 33557220
89 + 33557131 = 33557220
101 + 33557119 = 33557220
157 + 33557063 = 33557220
163 + 33557057 = 33557220
173 + 33557047 = 33557220
211 + 33557009 = 33557220

Showing the first eight; more decompositions exist.
