Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618400, here are decompositions:

41 + 33618359 = 33618400
71 + 33618329 = 33618400
83 + 33618317 = 33618400
149 + 33618251 = 33618400
191 + 33618209 = 33618400
227 + 33618173 = 33618400
239 + 33618161 = 33618400
251 + 33618149 = 33618400

Showing the first eight; more decompositions exist.
