Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497820, here are decompositions:
- 7 + 497813 = 497820
- 19 + 497801 = 497820
- 47 + 497773 = 497820
- 79 + 497741 = 497820
- 83 + 497737 = 497820
- 101 + 497719 = 497820
- 109 + 497711 = 497820
- 131 + 497689 = 497820
Showing the first eight; more decompositions exist.
