Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33568728, here are decompositions:

5 + 33568723 = 33568728
7 + 33568721 = 33568728
139 + 33568589 = 33568728
181 + 33568547 = 33568728
191 + 33568537 = 33568728
211 + 33568517 = 33568728
227 + 33568501 = 33568728
241 + 33568487 = 33568728

Showing the first eight; more decompositions exist.
