Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499450, here are decompositions:

11 + 499439 = 499450
47 + 499403 = 499450
53 + 499397 = 499450
59 + 499391 = 499450
89 + 499361 = 499450
101 + 499349 = 499450
167 + 499283 = 499450
173 + 499277 = 499450

Showing the first eight; more decompositions exist.
