Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10808, here are decompositions:
- 19 + 10789 = 10808
- 37 + 10771 = 10808
- 79 + 10729 = 10808
- 97 + 10711 = 10808
- 151 + 10657 = 10808
- 157 + 10651 = 10808
- 181 + 10627 = 10808
- 211 + 10597 = 10808
Showing the first eight; more decompositions exist.
