Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557280, here are decompositions:

23 + 33557257 = 33557280
83 + 33557197 = 33557280
137 + 33557143 = 33557280
149 + 33557131 = 33557280
179 + 33557101 = 33557280
193 + 33557087 = 33557280
223 + 33557057 = 33557280
233 + 33557047 = 33557280

Showing the first eight; more decompositions exist.
