Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479280, here are decompositions:

19 + 33479261 = 33479280
71 + 33479209 = 33479280
73 + 33479207 = 33479280
113 + 33479167 = 33479280
139 + 33479141 = 33479280
173 + 33479107 = 33479280
269 + 33479011 = 33479280
277 + 33479003 = 33479280

Showing the first eight; more decompositions exist.
