Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528980, here are decompositions:

19 + 33528961 = 33528980
97 + 33528883 = 33528980
139 + 33528841 = 33528980
151 + 33528829 = 33528980
157 + 33528823 = 33528980
211 + 33528769 = 33528980
229 + 33528751 = 33528980
241 + 33528739 = 33528980

Showing the first eight; more decompositions exist.
