Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498458, here are decompositions:

19 + 498439 = 498458
61 + 498397 = 498458
67 + 498391 = 498458
97 + 498361 = 498458
127 + 498331 = 498458
157 + 498301 = 498458
199 + 498259 = 498458
277 + 498181 = 498458

Showing the first eight; more decompositions exist.
