Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499618, here are decompositions:

11 + 499607 = 499618
17 + 499601 = 499618
47 + 499571 = 499618
59 + 499559 = 499618
137 + 499481 = 499618
179 + 499439 = 499618
227 + 499391 = 499618
257 + 499361 = 499618

Showing the first eight; more decompositions exist.
