Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33529280, here are decompositions:

3 + 33529277 = 33529280
67 + 33529213 = 33529280
97 + 33529183 = 33529280
157 + 33529123 = 33529280
193 + 33529087 = 33529280
349 + 33528931 = 33529280
397 + 33528883 = 33529280
439 + 33528841 = 33529280

Showing the first eight; more decompositions exist.
