Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498390, here are decompositions:

23 + 498367 = 498390
29 + 498361 = 498390
47 + 498343 = 498390
59 + 498331 = 498390
89 + 498301 = 498390
131 + 498259 = 498390
163 + 498227 = 498390
181 + 498209 = 498390

Showing the first eight; more decompositions exist.
