Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511878, here are decompositions:

17 + 33511861 = 33511878
89 + 33511789 = 33511878
109 + 33511769 = 33511878
149 + 33511729 = 33511878
151 + 33511727 = 33511878
181 + 33511697 = 33511878
199 + 33511679 = 33511878
251 + 33511627 = 33511878

Showing the first eight; more decompositions exist.
