Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18350, here are decompositions:
- 37 + 18313 = 18350
- 43 + 18307 = 18350
- 61 + 18289 = 18350
- 97 + 18253 = 18350
- 127 + 18223 = 18350
- 139 + 18211 = 18350
- 151 + 18199 = 18350
- 181 + 18169 = 18350
Showing the first eight; more decompositions exist.
