Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12644, here are decompositions:
- 3 + 12641 = 12644
- 7 + 12637 = 12644
- 31 + 12613 = 12644
- 43 + 12601 = 12644
- 61 + 12583 = 12644
- 67 + 12577 = 12644
- 97 + 12547 = 12644
- 103 + 12541 = 12644
Showing the first eight; more decompositions exist.
