Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18214, here are decompositions:
- 3 + 18211 = 18214
- 23 + 18191 = 18214
- 71 + 18143 = 18214
- 83 + 18131 = 18214
- 137 + 18077 = 18214
- 167 + 18047 = 18214
- 173 + 18041 = 18214
- 227 + 17987 = 18214
Showing the first eight; more decompositions exist.
