Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23720, here are decompositions:
- 31 + 23689 = 23720
- 43 + 23677 = 23720
- 97 + 23623 = 23720
- 127 + 23593 = 23720
- 139 + 23581 = 23720
- 157 + 23563 = 23720
- 163 + 23557 = 23720
- 181 + 23539 = 23720
Showing the first eight; more decompositions exist.
