Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6636, here are decompositions:
- 17 + 6619 = 6636
- 29 + 6607 = 6636
- 37 + 6599 = 6636
- 59 + 6577 = 6636
- 67 + 6569 = 6636
- 73 + 6563 = 6636
- 83 + 6553 = 6636
- 89 + 6547 = 6636
Showing the first eight; more decompositions exist.
