Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18262, here are decompositions:
- 5 + 18257 = 18262
- 11 + 18251 = 18262
- 29 + 18233 = 18262
- 71 + 18191 = 18262
- 113 + 18149 = 18262
- 131 + 18131 = 18262
- 173 + 18089 = 18262
- 281 + 17981 = 18262
Showing the first eight; more decompositions exist.
