Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2568, here are decompositions:
- 11 + 2557 = 2568
- 17 + 2551 = 2568
- 19 + 2549 = 2568
- 29 + 2539 = 2568
- 37 + 2531 = 2568
- 47 + 2521 = 2568
- 101 + 2467 = 2568
- 109 + 2459 = 2568
Showing the first eight; more decompositions exist.
