Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18026, here are decompositions:
- 13 + 18013 = 18026
- 37 + 17989 = 18026
- 67 + 17959 = 18026
- 97 + 17929 = 18026
- 103 + 17923 = 18026
- 163 + 17863 = 18026
- 199 + 17827 = 18026
- 277 + 17749 = 18026
Showing the first eight; more decompositions exist.
