Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497218, here are decompositions:

41 + 497177 = 497218
47 + 497171 = 497218
101 + 497117 = 497218
107 + 497111 = 497218
149 + 497069 = 497218
167 + 497051 = 497218
269 + 496949 = 497218
317 + 496901 = 497218

Showing the first eight; more decompositions exist.
