Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528820, here are decompositions:

23 + 33528797 = 33528820
53 + 33528767 = 33528820
89 + 33528731 = 33528820
113 + 33528707 = 33528820
131 + 33528689 = 33528820
167 + 33528653 = 33528820
191 + 33528629 = 33528820
293 + 33528527 = 33528820

Showing the first eight; more decompositions exist.
