Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497280, here are decompositions:
- 11 + 497269 = 497280
- 19 + 497261 = 497280
- 23 + 497257 = 497280
- 41 + 497239 = 497280
- 83 + 497197 = 497280
- 103 + 497177 = 497280
- 109 + 497171 = 497280
- 127 + 497153 = 497280
Showing the first eight; more decompositions exist.
