Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23690, here are decompositions:
- 3 + 23687 = 23690
- 13 + 23677 = 23690
- 19 + 23671 = 23690
- 61 + 23629 = 23690
- 67 + 23623 = 23690
- 97 + 23593 = 23690
- 109 + 23581 = 23690
- 127 + 23563 = 23690
Showing the first eight; more decompositions exist.
