Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499898, here are decompositions:

19 + 499879 = 499898
79 + 499819 = 499898
97 + 499801 = 499898
151 + 499747 = 499898
181 + 499717 = 499898
211 + 499687 = 499898
229 + 499669 = 499898
277 + 499621 = 499898

Showing the first eight; more decompositions exist.
