Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528228, here are decompositions:

7 + 33528221 = 33528228
17 + 33528211 = 33528228
61 + 33528167 = 33528228
79 + 33528149 = 33528228
137 + 33528091 = 33528228
179 + 33528049 = 33528228
211 + 33528017 = 33528228
229 + 33527999 = 33528228

Showing the first eight; more decompositions exist.
