Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491146, here are decompositions:

5 + 33491141 = 33491146
47 + 33491099 = 33491146
83 + 33491063 = 33491146
89 + 33491057 = 33491146
149 + 33490997 = 33491146
197 + 33490949 = 33491146
239 + 33490907 = 33491146
257 + 33490889 = 33491146

Showing the first eight; more decompositions exist.
