Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12600, here are decompositions:
- 11 + 12589 = 12600
- 17 + 12583 = 12600
- 23 + 12577 = 12600
- 31 + 12569 = 12600
- 47 + 12553 = 12600
- 53 + 12547 = 12600
- 59 + 12541 = 12600
- 61 + 12539 = 12600
Showing the first eight; more decompositions exist.
