Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499378, here are decompositions:

17 + 499361 = 499378
29 + 499349 = 499378
101 + 499277 = 499378
149 + 499229 = 499378
167 + 499211 = 499378
197 + 499181 = 499378
227 + 499151 = 499378
239 + 499139 = 499378

Showing the first eight; more decompositions exist.
