Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518418, here are decompositions:

29 + 33518389 = 33518418
67 + 33518351 = 33518418
149 + 33518269 = 33518418
151 + 33518267 = 33518418
179 + 33518239 = 33518418
277 + 33518141 = 33518418
281 + 33518137 = 33518418
337 + 33518081 = 33518418

Showing the first eight; more decompositions exist.
