Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528642, here are decompositions:

5 + 33528637 = 33528642
11 + 33528631 = 33528642
13 + 33528629 = 33528642
29 + 33528613 = 33528642
131 + 33528511 = 33528642
151 + 33528491 = 33528642
163 + 33528479 = 33528642
179 + 33528463 = 33528642

Showing the first eight; more decompositions exist.
