Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528638, here are decompositions:

7 + 33528631 = 33528638
127 + 33528511 = 33528638
139 + 33528499 = 33528638
271 + 33528367 = 33528638
277 + 33528361 = 33528638
331 + 33528307 = 33528638
349 + 33528289 = 33528638
397 + 33528241 = 33528638

Showing the first eight; more decompositions exist.
