Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18234, here are decompositions:
- 5 + 18229 = 18234
- 11 + 18223 = 18234
- 17 + 18217 = 18234
- 23 + 18211 = 18234
- 43 + 18191 = 18234
- 53 + 18181 = 18234
- 101 + 18133 = 18234
- 103 + 18131 = 18234
Showing the first eight; more decompositions exist.
