Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478688, here are decompositions:

7 + 33478681 = 33478688
37 + 33478651 = 33478688
79 + 33478609 = 33478688
127 + 33478561 = 33478688
157 + 33478531 = 33478688
211 + 33478477 = 33478688
277 + 33478411 = 33478688
457 + 33478231 = 33478688

Showing the first eight; more decompositions exist.
