Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11568, here are decompositions:
- 17 + 11551 = 11568
- 19 + 11549 = 11568
- 41 + 11527 = 11568
- 71 + 11497 = 11568
- 79 + 11489 = 11568
- 97 + 11471 = 11568
- 101 + 11467 = 11568
- 131 + 11437 = 11568
Showing the first eight; more decompositions exist.
