Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18252, here are decompositions:
- 19 + 18233 = 18252
- 23 + 18229 = 18252
- 29 + 18223 = 18252
- 41 + 18211 = 18252
- 53 + 18199 = 18252
- 61 + 18191 = 18252
- 71 + 18181 = 18252
- 83 + 18169 = 18252
Showing the first eight; more decompositions exist.
