Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499408, here are decompositions:

5 + 499403 = 499408
11 + 499397 = 499408
17 + 499391 = 499408
47 + 499361 = 499408
59 + 499349 = 499408
131 + 499277 = 499408
179 + 499229 = 499408
197 + 499211 = 499408

Showing the first eight; more decompositions exist.
