Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478788, here are decompositions:

29 + 33478759 = 33478788
37 + 33478751 = 33478788
61 + 33478727 = 33478788
67 + 33478721 = 33478788
107 + 33478681 = 33478788
137 + 33478651 = 33478788
139 + 33478649 = 33478788
179 + 33478609 = 33478788

Showing the first eight; more decompositions exist.
