Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12736, here are decompositions:
- 23 + 12713 = 12736
- 47 + 12689 = 12736
- 83 + 12653 = 12736
- 89 + 12647 = 12736
- 167 + 12569 = 12736
- 197 + 12539 = 12736
- 233 + 12503 = 12736
- 239 + 12497 = 12736
Showing the first eight; more decompositions exist.
