Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23140, here are decompositions:
- 23 + 23117 = 23140
- 41 + 23099 = 23140
- 53 + 23087 = 23140
- 59 + 23081 = 23140
- 83 + 23057 = 23140
- 101 + 23039 = 23140
- 113 + 23027 = 23140
- 137 + 23003 = 23140
Showing the first eight; more decompositions exist.
