Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478666, here are decompositions:

17 + 33478649 = 33478666
59 + 33478607 = 33478666
83 + 33478583 = 33478666
149 + 33478517 = 33478666
197 + 33478469 = 33478666
227 + 33478439 = 33478666
233 + 33478433 = 33478666
359 + 33478307 = 33478666

Showing the first eight; more decompositions exist.
