Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518388, here are decompositions:

37 + 33518351 = 33518388
61 + 33518327 = 33518388
149 + 33518239 = 33518388
179 + 33518209 = 33518388
251 + 33518137 = 33518388
257 + 33518131 = 33518388
269 + 33518119 = 33518388
307 + 33518081 = 33518388

Showing the first eight; more decompositions exist.
