Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18250, here are decompositions:
- 17 + 18233 = 18250
- 59 + 18191 = 18250
- 101 + 18149 = 18250
- 107 + 18143 = 18250
- 131 + 18119 = 18250
- 173 + 18077 = 18250
- 191 + 18059 = 18250
- 263 + 17987 = 18250
Showing the first eight; more decompositions exist.
