Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23000, here are decompositions:
- 7 + 22993 = 23000
- 37 + 22963 = 23000
- 79 + 22921 = 23000
- 139 + 22861 = 23000
- 193 + 22807 = 23000
- 223 + 22777 = 23000
- 283 + 22717 = 23000
- 331 + 22669 = 23000
Showing the first eight; more decompositions exist.
