Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23806, here are decompositions:
- 5 + 23801 = 23806
- 17 + 23789 = 23806
- 53 + 23753 = 23806
- 59 + 23747 = 23806
- 137 + 23669 = 23806
- 173 + 23633 = 23806
- 179 + 23627 = 23806
- 197 + 23609 = 23806
Showing the first eight; more decompositions exist.
