Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23518, here are decompositions:
- 59 + 23459 = 23518
- 71 + 23447 = 23518
- 101 + 23417 = 23518
- 149 + 23369 = 23518
- 179 + 23339 = 23518
- 191 + 23327 = 23518
- 197 + 23321 = 23518
- 227 + 23291 = 23518
Showing the first eight; more decompositions exist.
