Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 496640, here are decompositions:

31 + 496609 = 496640
61 + 496579 = 496640
163 + 496477 = 496640
181 + 496459 = 496640
241 + 496399 = 496640
307 + 496333 = 496640
337 + 496303 = 496640
349 + 496291 = 496640

Showing the first eight; more decompositions exist.
