Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499238, here are decompositions:

79 + 499159 = 499238
97 + 499141 = 499238
109 + 499129 = 499238
139 + 499099 = 499238
199 + 499039 = 499238
211 + 499027 = 499238
277 + 498961 = 499238
307 + 498931 = 499238

Showing the first eight; more decompositions exist.
