Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479220, here are decompositions:

11 + 33479209 = 33479220
13 + 33479207 = 33479220
53 + 33479167 = 33479220
59 + 33479161 = 33479220
79 + 33479141 = 33479220
101 + 33479119 = 33479220
113 + 33479107 = 33479220
157 + 33479063 = 33479220

Showing the first eight; more decompositions exist.
