Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528020, here are decompositions:

3 + 33528017 = 33528020
7 + 33528013 = 33528020
13 + 33528007 = 33528020
73 + 33527947 = 33528020
79 + 33527941 = 33528020
139 + 33527881 = 33528020
151 + 33527869 = 33528020
157 + 33527863 = 33528020

Showing the first eight; more decompositions exist.
