Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512868, here are decompositions:

29 + 33512839 = 33512868
31 + 33512837 = 33512868
61 + 33512807 = 33512868
89 + 33512779 = 33512868
197 + 33512671 = 33512868
227 + 33512641 = 33512868
239 + 33512629 = 33512868
251 + 33512617 = 33512868

Showing the first eight; more decompositions exist.
