Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528660, here are decompositions:

7 + 33528653 = 33528660
23 + 33528637 = 33528660
29 + 33528631 = 33528660
31 + 33528629 = 33528660
43 + 33528617 = 33528660
47 + 33528613 = 33528660
149 + 33528511 = 33528660
163 + 33528497 = 33528660

Showing the first eight; more decompositions exist.
