Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478782, here are decompositions:

23 + 33478759 = 33478782
31 + 33478751 = 33478782
59 + 33478723 = 33478782
61 + 33478721 = 33478782
89 + 33478693 = 33478782
101 + 33478681 = 33478782
131 + 33478651 = 33478782
173 + 33478609 = 33478782

Showing the first eight; more decompositions exist.
