Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497220, here are decompositions:

23 + 497197 = 497220
43 + 497177 = 497220
67 + 497153 = 497220
79 + 497141 = 497220
83 + 497137 = 497220
103 + 497117 = 497220
107 + 497113 = 497220
109 + 497111 = 497220

Showing the first eight; more decompositions exist.
