Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528280, here are decompositions:

11 + 33528269 = 33528280
59 + 33528221 = 33528280
113 + 33528167 = 33528280
131 + 33528149 = 33528280
239 + 33528041 = 33528280
257 + 33528023 = 33528280
263 + 33528017 = 33528280
281 + 33527999 = 33528280

Showing the first eight; more decompositions exist.
