Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499666, here are decompositions:

3 + 499663 = 499666
5 + 499661 = 499666
17 + 499649 = 499666
29 + 499637 = 499666
59 + 499607 = 499666
107 + 499559 = 499666
173 + 499493 = 499666
227 + 499439 = 499666

Showing the first eight; more decompositions exist.
