Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499868, here are decompositions:

67 + 499801 = 499868
139 + 499729 = 499868
151 + 499717 = 499868
157 + 499711 = 499868
181 + 499687 = 499868
199 + 499669 = 499868
277 + 499591 = 499868
349 + 499519 = 499868

Showing the first eight; more decompositions exist.
