Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23664, here are decompositions:
- 31 + 23633 = 23664
- 37 + 23627 = 23664
- 41 + 23623 = 23664
- 61 + 23603 = 23664
- 71 + 23593 = 23664
- 83 + 23581 = 23664
- 97 + 23567 = 23664
- 101 + 23563 = 23664
Showing the first eight; more decompositions exist.
