Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478566, here are decompositions:

5 + 33478561 = 33478566
89 + 33478477 = 33478566
97 + 33478469 = 33478566
127 + 33478439 = 33478566
179 + 33478387 = 33478566
229 + 33478337 = 33478566
283 + 33478283 = 33478566
293 + 33478273 = 33478566

Showing the first eight; more decompositions exist.
