Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999518, here are decompositions:

19 + 999499 = 999518
67 + 999451 = 999518
211 + 999307 = 999518
337 + 999181 = 999518
349 + 999169 = 999518
571 + 998947 = 999518
577 + 998941 = 999518
601 + 998917 = 999518

Showing the first eight; more decompositions exist.
