Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22638, here are decompositions:
- 17 + 22621 = 22638
- 19 + 22619 = 22638
- 67 + 22571 = 22638
- 71 + 22567 = 22638
- 89 + 22549 = 22638
- 97 + 22541 = 22638
- 107 + 22531 = 22638
- 127 + 22511 = 22638
Showing the first eight; more decompositions exist.
