Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557238, here are decompositions:

41 + 33557197 = 33557238
107 + 33557131 = 33557238
137 + 33557101 = 33557238
151 + 33557087 = 33557238
181 + 33557057 = 33557238
191 + 33557047 = 33557238
227 + 33557011 = 33557238
229 + 33557009 = 33557238

Showing the first eight; more decompositions exist.
