Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505428, here are decompositions:

67 + 33505361 = 33505428
127 + 33505301 = 33505428
167 + 33505261 = 33505428
181 + 33505247 = 33505428
199 + 33505229 = 33505428
241 + 33505187 = 33505428
251 + 33505177 = 33505428
311 + 33505117 = 33505428

Showing the first eight; more decompositions exist.
