Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478540, here are decompositions:

23 + 33478517 = 33478540
71 + 33478469 = 33478540
101 + 33478439 = 33478540
107 + 33478433 = 33478540
149 + 33478391 = 33478540
233 + 33478307 = 33478540
257 + 33478283 = 33478540
419 + 33478121 = 33478540

Showing the first eight; more decompositions exist.
