Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23808, here are decompositions:
- 7 + 23801 = 23808
- 19 + 23789 = 23808
- 41 + 23767 = 23808
- 47 + 23761 = 23808
- 61 + 23747 = 23808
- 67 + 23741 = 23808
- 89 + 23719 = 23808
- 131 + 23677 = 23808
Showing the first eight; more decompositions exist.
