Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23680, here are decompositions:
- 3 + 23677 = 23680
- 11 + 23669 = 23680
- 17 + 23663 = 23680
- 47 + 23633 = 23680
- 53 + 23627 = 23680
- 71 + 23609 = 23680
- 113 + 23567 = 23680
- 131 + 23549 = 23680
Showing the first eight; more decompositions exist.
