Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8556, here are decompositions:
- 13 + 8543 = 8556
- 17 + 8539 = 8556
- 19 + 8537 = 8556
- 29 + 8527 = 8556
- 43 + 8513 = 8556
- 89 + 8467 = 8556
- 109 + 8447 = 8556
- 113 + 8443 = 8556
Showing the first eight; more decompositions exist.
