Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499808, here are decompositions:

7 + 499801 = 499808
61 + 499747 = 499808
79 + 499729 = 499808
97 + 499711 = 499808
139 + 499669 = 499808
349 + 499459 = 499808
487 + 499321 = 499808
499 + 499309 = 499808

Showing the first eight; more decompositions exist.
