Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478512, here are decompositions:

43 + 33478469 = 33478512
73 + 33478439 = 33478512
79 + 33478433 = 33478512
101 + 33478411 = 33478512
181 + 33478331 = 33478512
229 + 33478283 = 33478512
239 + 33478273 = 33478512
281 + 33478231 = 33478512

Showing the first eight; more decompositions exist.
