Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479388, here are decompositions:

11 + 33479377 = 33479388
17 + 33479371 = 33479388
37 + 33479351 = 33479388
71 + 33479317 = 33479388
109 + 33479279 = 33479388
127 + 33479261 = 33479388
157 + 33479231 = 33479388
179 + 33479209 = 33479388

Showing the first eight; more decompositions exist.
