Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528140, here are decompositions:

3 + 33528137 = 33528140
31 + 33528109 = 33528140
73 + 33528067 = 33528140
127 + 33528013 = 33528140
193 + 33527947 = 33528140
199 + 33527941 = 33528140
211 + 33527929 = 33528140
241 + 33527899 = 33528140

Showing the first eight; more decompositions exist.
