Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505280, here are decompositions:

19 + 33505261 = 33505280
103 + 33505177 = 33505280
157 + 33505123 = 33505280
163 + 33505117 = 33505280
223 + 33505057 = 33505280
229 + 33505051 = 33505280
241 + 33505039 = 33505280
271 + 33505009 = 33505280

Showing the first eight; more decompositions exist.
