Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18116, here are decompositions:
- 19 + 18097 = 18116
- 67 + 18049 = 18116
- 73 + 18043 = 18116
- 103 + 18013 = 18116
- 127 + 17989 = 18116
- 139 + 17977 = 18116
- 157 + 17959 = 18116
- 193 + 17923 = 18116
Showing the first eight; more decompositions exist.
