Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23840, here are decompositions:
- 7 + 23833 = 23840
- 13 + 23827 = 23840
- 67 + 23773 = 23840
- 73 + 23767 = 23840
- 79 + 23761 = 23840
- 97 + 23743 = 23840
- 151 + 23689 = 23840
- 163 + 23677 = 23840
Showing the first eight; more decompositions exist.
