Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489540, here are decompositions:

37 + 33489503 = 33489540
107 + 33489433 = 33489540
109 + 33489431 = 33489540
163 + 33489377 = 33489540
179 + 33489361 = 33489540
191 + 33489349 = 33489540
199 + 33489341 = 33489540
257 + 33489283 = 33489540

Showing the first eight; more decompositions exist.
