Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518450, here are decompositions:

13 + 33518437 = 33518450
61 + 33518389 = 33518450
157 + 33518293 = 33518450
181 + 33518269 = 33518450
211 + 33518239 = 33518450
241 + 33518209 = 33518450
313 + 33518137 = 33518450
331 + 33518119 = 33518450

Showing the first eight; more decompositions exist.
