Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22560, here are decompositions:
- 11 + 22549 = 22560
- 17 + 22543 = 22560
- 19 + 22541 = 22560
- 29 + 22531 = 22560
- 59 + 22501 = 22560
- 79 + 22481 = 22560
- 107 + 22453 = 22560
- 113 + 22447 = 22560
Showing the first eight; more decompositions exist.
