Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498378, here are decompositions:

11 + 498367 = 498378
17 + 498361 = 498378
47 + 498331 = 498378
107 + 498271 = 498378
151 + 498227 = 498378
197 + 498181 = 498378
211 + 498167 = 498378
277 + 498101 = 498378

Showing the first eight; more decompositions exist.
