Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18286, here are decompositions:
- 17 + 18269 = 18286
- 29 + 18257 = 18286
- 53 + 18233 = 18286
- 137 + 18149 = 18286
- 167 + 18119 = 18286
- 197 + 18089 = 18286
- 227 + 18059 = 18286
- 239 + 18047 = 18286
Showing the first eight; more decompositions exist.
