Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528880, here are decompositions:

41 + 33528839 = 33528880
59 + 33528821 = 33528880
83 + 33528797 = 33528880
113 + 33528767 = 33528880
149 + 33528731 = 33528880
173 + 33528707 = 33528880
191 + 33528689 = 33528880
227 + 33528653 = 33528880

Showing the first eight; more decompositions exist.
