Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499458, here are decompositions:

19 + 499439 = 499458
61 + 499397 = 499458
67 + 499391 = 499458
97 + 499361 = 499458
109 + 499349 = 499458
131 + 499327 = 499458
137 + 499321 = 499458
149 + 499309 = 499458

Showing the first eight; more decompositions exist.
