Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499390, here are decompositions:

29 + 499361 = 499390
41 + 499349 = 499390
107 + 499283 = 499390
113 + 499277 = 499390
137 + 499253 = 499390
179 + 499211 = 499390
233 + 499157 = 499390
239 + 499151 = 499390

Showing the first eight; more decompositions exist.
