Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707800, here are decompositions:
- 7 + 8707793 = 8707800
- 19 + 8707781 = 8707800
- 37 + 8707763 = 8707800
- 47 + 8707753 = 8707800
- 53 + 8707747 = 8707800
- 89 + 8707711 = 8707800
- 103 + 8707697 = 8707800
- 113 + 8707687 = 8707800
Showing the first eight; more decompositions exist.
