Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505540, here are decompositions:

41 + 33505499 = 33505540
137 + 33505403 = 33505540
179 + 33505361 = 33505540
239 + 33505301 = 33505540
293 + 33505247 = 33505540
311 + 33505229 = 33505540
353 + 33505187 = 33505540
491 + 33505049 = 33505540

Showing the first eight; more decompositions exist.
