Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528640, here are decompositions:

3 + 33528637 = 33528640
11 + 33528629 = 33528640
23 + 33528617 = 33528640
113 + 33528527 = 33528640
149 + 33528491 = 33528640
263 + 33528377 = 33528640
419 + 33528221 = 33528640
491 + 33528149 = 33528640

Showing the first eight; more decompositions exist.
