Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478480, here are decompositions:

3 + 33478477 = 33478480
11 + 33478469 = 33478480
41 + 33478439 = 33478480
47 + 33478433 = 33478480
59 + 33478421 = 33478480
89 + 33478391 = 33478480
149 + 33478331 = 33478480
173 + 33478307 = 33478480

Showing the first eight; more decompositions exist.
