Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23940, here are decompositions:
- 11 + 23929 = 23940
- 23 + 23917 = 23940
- 29 + 23911 = 23940
- 31 + 23909 = 23940
- 41 + 23899 = 23940
- 47 + 23893 = 23940
- 53 + 23887 = 23940
- 61 + 23879 = 23940
Showing the first eight; more decompositions exist.
