Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12188, here are decompositions:
- 31 + 12157 = 12188
- 79 + 12109 = 12188
- 139 + 12049 = 12188
- 151 + 12037 = 12188
- 181 + 12007 = 12188
- 229 + 11959 = 12188
- 349 + 11839 = 12188
- 367 + 11821 = 12188
Showing the first eight; more decompositions exist.
