Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18236, here are decompositions:
- 3 + 18233 = 18236
- 7 + 18229 = 18236
- 13 + 18223 = 18236
- 19 + 18217 = 18236
- 37 + 18199 = 18236
- 67 + 18169 = 18236
- 103 + 18133 = 18236
- 109 + 18127 = 18236
Showing the first eight; more decompositions exist.
