Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498220, here are decompositions:

11 + 498209 = 498220
53 + 498167 = 498220
101 + 498119 = 498220
131 + 498089 = 498220
167 + 498053 = 498220
227 + 497993 = 498220
251 + 497969 = 498220
257 + 497963 = 498220

Showing the first eight; more decompositions exist.
