Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18184, here are decompositions:
- 3 + 18181 = 18184
- 41 + 18143 = 18184
- 53 + 18131 = 18184
- 107 + 18077 = 18184
- 137 + 18047 = 18184
- 197 + 17987 = 18184
- 227 + 17957 = 18184
- 263 + 17921 = 18184
Showing the first eight; more decompositions exist.
