Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33573640, here are decompositions:

29 + 33573611 = 33573640
59 + 33573581 = 33573640
167 + 33573473 = 33573640
197 + 33573443 = 33573640
227 + 33573413 = 33573640
239 + 33573401 = 33573640
251 + 33573389 = 33573640
281 + 33573359 = 33573640

Showing the first eight; more decompositions exist.
