Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478618, here are decompositions:

11 + 33478607 = 33478618
101 + 33478517 = 33478618
149 + 33478469 = 33478618
179 + 33478439 = 33478618
197 + 33478421 = 33478618
227 + 33478391 = 33478618
281 + 33478337 = 33478618
311 + 33478307 = 33478618

Showing the first eight; more decompositions exist.
