Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499688, here are decompositions:

19 + 499669 = 499688
67 + 499621 = 499688
97 + 499591 = 499688
139 + 499549 = 499688
181 + 499507 = 499688
229 + 499459 = 499688
367 + 499321 = 499688
379 + 499309 = 499688

Showing the first eight; more decompositions exist.
