Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528620, here are decompositions:

3 + 33528617 = 33528620
7 + 33528613 = 33528620
109 + 33528511 = 33528620
157 + 33528463 = 33528620
283 + 33528337 = 33528620
313 + 33528307 = 33528620
331 + 33528289 = 33528620
379 + 33528241 = 33528620

Showing the first eight; more decompositions exist.
