Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528720, here are decompositions:

13 + 33528707 = 33528720
31 + 33528689 = 33528720
41 + 33528679 = 33528720
61 + 33528659 = 33528720
67 + 33528653 = 33528720
83 + 33528637 = 33528720
89 + 33528631 = 33528720
103 + 33528617 = 33528720

Showing the first eight; more decompositions exist.
