Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18108, here are decompositions:
- 11 + 18097 = 18108
- 19 + 18089 = 18108
- 31 + 18077 = 18108
- 47 + 18061 = 18108
- 59 + 18049 = 18108
- 61 + 18047 = 18108
- 67 + 18041 = 18108
- 127 + 17981 = 18108
Showing the first eight; more decompositions exist.
