Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494656, here are decompositions:

5 + 494651 = 494656
17 + 494639 = 494656
47 + 494609 = 494656
89 + 494567 = 494656
137 + 494519 = 494656
269 + 494387 = 494656
389 + 494267 = 494656
419 + 494237 = 494656

Showing the first eight; more decompositions exist.
