Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478456, here are decompositions:

17 + 33478439 = 33478456
23 + 33478433 = 33478456
149 + 33478307 = 33478456
173 + 33478283 = 33478456
257 + 33478199 = 33478456
293 + 33478163 = 33478456
359 + 33478097 = 33478456
443 + 33478013 = 33478456

Showing the first eight; more decompositions exist.
