Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12636, here are decompositions:
- 17 + 12619 = 12636
- 23 + 12613 = 12636
- 47 + 12589 = 12636
- 53 + 12583 = 12636
- 59 + 12577 = 12636
- 67 + 12569 = 12636
- 83 + 12553 = 12636
- 89 + 12547 = 12636
Showing the first eight; more decompositions exist.
