Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478878, here are decompositions:

71 + 33478807 = 33478878
127 + 33478751 = 33478878
151 + 33478727 = 33478878
157 + 33478721 = 33478878
197 + 33478681 = 33478878
227 + 33478651 = 33478878
229 + 33478649 = 33478878
269 + 33478609 = 33478878

Showing the first eight; more decompositions exist.
