Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528400, here are decompositions:

23 + 33528377 = 33528400
131 + 33528269 = 33528400
179 + 33528221 = 33528400
233 + 33528167 = 33528400
251 + 33528149 = 33528400
263 + 33528137 = 33528400
359 + 33528041 = 33528400
383 + 33528017 = 33528400

Showing the first eight; more decompositions exist.
