Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499686, here are decompositions:

7 + 499679 = 499686
13 + 499673 = 499686
17 + 499669 = 499686
23 + 499663 = 499686
37 + 499649 = 499686
53 + 499633 = 499686
79 + 499607 = 499686
127 + 499559 = 499686

Showing the first eight; more decompositions exist.
