Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12388, here are decompositions:
- 11 + 12377 = 12388
- 41 + 12347 = 12388
- 59 + 12329 = 12388
- 107 + 12281 = 12388
- 137 + 12251 = 12388
- 149 + 12239 = 12388
- 191 + 12197 = 12388
- 227 + 12161 = 12388
Showing the first eight; more decompositions exist.
