Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528320, here are decompositions:

13 + 33528307 = 33528320
31 + 33528289 = 33528320
79 + 33528241 = 33528320
109 + 33528211 = 33528320
127 + 33528193 = 33528320
157 + 33528163 = 33528320
211 + 33528109 = 33528320
229 + 33528091 = 33528320

Showing the first eight; more decompositions exist.
