Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12660, here are decompositions:
- 7 + 12653 = 12660
- 13 + 12647 = 12660
- 19 + 12641 = 12660
- 23 + 12637 = 12660
- 41 + 12619 = 12660
- 47 + 12613 = 12660
- 59 + 12601 = 12660
- 71 + 12589 = 12660
Showing the first eight; more decompositions exist.
