Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528420, here are decompositions:

43 + 33528377 = 33528420
47 + 33528373 = 33528420
53 + 33528367 = 33528420
59 + 33528361 = 33528420
83 + 33528337 = 33528420
113 + 33528307 = 33528420
131 + 33528289 = 33528420
151 + 33528269 = 33528420

Showing the first eight; more decompositions exist.
