Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33495728, here are decompositions:

31 + 33495697 = 33495728
151 + 33495577 = 33495728
181 + 33495547 = 33495728
241 + 33495487 = 33495728
337 + 33495391 = 33495728
499 + 33495229 = 33495728
691 + 33495037 = 33495728
709 + 33495019 = 33495728

Showing the first eight; more decompositions exist.
