Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498280, here are decompositions:

23 + 498257 = 498280
53 + 498227 = 498280
71 + 498209 = 498280
113 + 498167 = 498280
137 + 498143 = 498280
179 + 498101 = 498280
191 + 498089 = 498280
227 + 498053 = 498280

Showing the first eight; more decompositions exist.
