Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12732, here are decompositions:
- 11 + 12721 = 12732
- 19 + 12713 = 12732
- 29 + 12703 = 12732
- 43 + 12689 = 12732
- 61 + 12671 = 12732
- 73 + 12659 = 12732
- 79 + 12653 = 12732
- 113 + 12619 = 12732
Showing the first eight; more decompositions exist.
