Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499660, here are decompositions:

11 + 499649 = 499660
23 + 499637 = 499660
53 + 499607 = 499660
59 + 499601 = 499660
89 + 499571 = 499660
101 + 499559 = 499660
137 + 499523 = 499660
167 + 499493 = 499660

Showing the first eight; more decompositions exist.
