Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23828, here are decompositions:
- 61 + 23767 = 23828
- 67 + 23761 = 23828
- 109 + 23719 = 23828
- 139 + 23689 = 23828
- 151 + 23677 = 23828
- 157 + 23671 = 23828
- 199 + 23629 = 23828
- 229 + 23599 = 23828
Showing the first eight; more decompositions exist.
