Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499518, here are decompositions:

11 + 499507 = 499518
37 + 499481 = 499518
59 + 499459 = 499518
79 + 499439 = 499518
127 + 499391 = 499518
157 + 499361 = 499518
191 + 499327 = 499518
197 + 499321 = 499518

Showing the first eight; more decompositions exist.
