Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8568, here are decompositions:
- 5 + 8563 = 8568
- 29 + 8539 = 8568
- 31 + 8537 = 8568
- 41 + 8527 = 8568
- 47 + 8521 = 8568
- 67 + 8501 = 8568
- 101 + 8467 = 8568
- 107 + 8461 = 8568
Showing the first eight; more decompositions exist.
