Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497240, here are decompositions:

43 + 497197 = 497240
103 + 497137 = 497240
127 + 497113 = 497240
193 + 497047 = 497240
199 + 497041 = 497240
223 + 497017 = 497240
229 + 497011 = 497240
241 + 496999 = 497240

Showing the first eight; more decompositions exist.
