Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497290, here are decompositions:

11 + 497279 = 497290
29 + 497261 = 497290
113 + 497177 = 497290
137 + 497153 = 497290
149 + 497141 = 497290
173 + 497117 = 497290
179 + 497111 = 497290
197 + 497093 = 497290

Showing the first eight; more decompositions exist.
