Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499428, here are decompositions:

5 + 499423 = 499428
31 + 499397 = 499428
37 + 499391 = 499428
67 + 499361 = 499428
79 + 499349 = 499428
101 + 499327 = 499428
107 + 499321 = 499428
151 + 499277 = 499428

Showing the first eight; more decompositions exist.
