Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23666, here are decompositions:
- 3 + 23663 = 23666
- 37 + 23629 = 23666
- 43 + 23623 = 23666
- 67 + 23599 = 23666
- 73 + 23593 = 23666
- 103 + 23563 = 23666
- 109 + 23557 = 23666
- 127 + 23539 = 23666
Showing the first eight; more decompositions exist.
