Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478686, here are decompositions:

5 + 33478681 = 33478686
37 + 33478649 = 33478686
79 + 33478607 = 33478686
103 + 33478583 = 33478686
349 + 33478337 = 33478686
379 + 33478307 = 33478686
487 + 33478199 = 33478686
503 + 33478183 = 33478686

Showing the first eight; more decompositions exist.
