Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528920, here are decompositions:

37 + 33528883 = 33528920
79 + 33528841 = 33528920
97 + 33528823 = 33528920
127 + 33528793 = 33528920
151 + 33528769 = 33528920
181 + 33528739 = 33528920
199 + 33528721 = 33528920
241 + 33528679 = 33528920

Showing the first eight; more decompositions exist.
