Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18154, here are decompositions:
- 5 + 18149 = 18154
- 11 + 18143 = 18154
- 23 + 18131 = 18154
- 107 + 18047 = 18154
- 113 + 18041 = 18154
- 167 + 17987 = 18154
- 173 + 17981 = 18154
- 197 + 17957 = 18154
Showing the first eight; more decompositions exist.
