Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528220, here are decompositions:

53 + 33528167 = 33528220
71 + 33528149 = 33528220
83 + 33528137 = 33528220
179 + 33528041 = 33528220
197 + 33528023 = 33528220
227 + 33527993 = 33528220
239 + 33527981 = 33528220
251 + 33527969 = 33528220

Showing the first eight; more decompositions exist.
