Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490278, here are decompositions:

7 + 33490271 = 33490278
37 + 33490241 = 33490278
67 + 33490211 = 33490278
71 + 33490207 = 33490278
89 + 33490189 = 33490278
97 + 33490181 = 33490278
181 + 33490097 = 33490278
271 + 33490007 = 33490278

Showing the first eight; more decompositions exist.
