Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499530, here are decompositions:

7 + 499523 = 499530
11 + 499519 = 499530
23 + 499507 = 499530
37 + 499493 = 499530
47 + 499483 = 499530
71 + 499459 = 499530
107 + 499423 = 499530
127 + 499403 = 499530

Showing the first eight; more decompositions exist.
