Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478656, here are decompositions:

5 + 33478651 = 33478656
7 + 33478649 = 33478656
47 + 33478609 = 33478656
73 + 33478583 = 33478656
139 + 33478517 = 33478656
179 + 33478477 = 33478656
223 + 33478433 = 33478656
269 + 33478387 = 33478656

Showing the first eight; more decompositions exist.
