Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497278, here are decompositions:

17 + 497261 = 497278
101 + 497177 = 497278
107 + 497171 = 497278
137 + 497141 = 497278
167 + 497111 = 497278
227 + 497051 = 497278
281 + 496997 = 497278
359 + 496919 = 497278

Showing the first eight; more decompositions exist.
