Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478458, here are decompositions:

19 + 33478439 = 33478458
37 + 33478421 = 33478458
47 + 33478411 = 33478458
67 + 33478391 = 33478458
71 + 33478387 = 33478458
127 + 33478331 = 33478458
151 + 33478307 = 33478458
227 + 33478231 = 33478458

Showing the first eight; more decompositions exist.
