Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528690, here are decompositions:

11 + 33528679 = 33528690
31 + 33528659 = 33528690
37 + 33528653 = 33528690
53 + 33528637 = 33528690
59 + 33528631 = 33528690
61 + 33528629 = 33528690
73 + 33528617 = 33528690
163 + 33528527 = 33528690

Showing the first eight; more decompositions exist.
