Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18106, here are decompositions:
- 17 + 18089 = 18106
- 29 + 18077 = 18106
- 47 + 18059 = 18106
- 59 + 18047 = 18106
- 149 + 17957 = 18106
- 167 + 17939 = 18106
- 197 + 17909 = 18106
- 269 + 17837 = 18106
Showing the first eight; more decompositions exist.
