Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33502640, here are decompositions:

79 + 33502561 = 33502640
97 + 33502543 = 33502640
151 + 33502489 = 33502640
163 + 33502477 = 33502640
211 + 33502429 = 33502640
277 + 33502363 = 33502640
313 + 33502327 = 33502640
373 + 33502267 = 33502640

Showing the first eight; more decompositions exist.
