Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478660, here are decompositions:

11 + 33478649 = 33478660
53 + 33478607 = 33478660
191 + 33478469 = 33478660
227 + 33478433 = 33478660
239 + 33478421 = 33478660
269 + 33478391 = 33478660
353 + 33478307 = 33478660
461 + 33478199 = 33478660

Showing the first eight; more decompositions exist.
