Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43808, here are decompositions:
- 7 + 43801 = 43808
- 19 + 43789 = 43808
- 31 + 43777 = 43808
- 97 + 43711 = 43808
- 139 + 43669 = 43808
- 157 + 43651 = 43808
- 181 + 43627 = 43808
- 199 + 43609 = 43808
Showing the first eight; more decompositions exist.
