Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478866, here are decompositions:

59 + 33478807 = 33478866
107 + 33478759 = 33478866
139 + 33478727 = 33478866
173 + 33478693 = 33478866
257 + 33478609 = 33478866
283 + 33478583 = 33478866
349 + 33478517 = 33478866
389 + 33478477 = 33478866

Showing the first eight; more decompositions exist.
