Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499538, here are decompositions:

19 + 499519 = 499538
31 + 499507 = 499538
79 + 499459 = 499538
211 + 499327 = 499538
229 + 499309 = 499538
271 + 499267 = 499538
349 + 499189 = 499538
379 + 499159 = 499538

Showing the first eight; more decompositions exist.
