Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499500, here are decompositions:

7 + 499493 = 499500
17 + 499483 = 499500
19 + 499481 = 499500
41 + 499459 = 499500
61 + 499439 = 499500
97 + 499403 = 499500
103 + 499397 = 499500
109 + 499391 = 499500

Showing the first eight; more decompositions exist.
