Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18226, here are decompositions:
- 3 + 18223 = 18226
- 83 + 18143 = 18226
- 107 + 18119 = 18226
- 137 + 18089 = 18226
- 149 + 18077 = 18226
- 167 + 18059 = 18226
- 179 + 18047 = 18226
- 239 + 17987 = 18226
Showing the first eight; more decompositions exist.
