Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478770, here are decompositions:

11 + 33478759 = 33478770
19 + 33478751 = 33478770
43 + 33478727 = 33478770
47 + 33478723 = 33478770
89 + 33478681 = 33478770
163 + 33478607 = 33478770
239 + 33478531 = 33478770
293 + 33478477 = 33478770

Showing the first eight; more decompositions exist.
