Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528644, here are decompositions:

7 + 33528637 = 33528644
13 + 33528631 = 33528644
31 + 33528613 = 33528644
181 + 33528463 = 33528644
271 + 33528373 = 33528644
277 + 33528367 = 33528644
283 + 33528361 = 33528644
307 + 33528337 = 33528644

Showing the first eight; more decompositions exist.
