Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26280, here are decompositions:
- 13 + 26267 = 26280
- 17 + 26263 = 26280
- 19 + 26261 = 26280
- 29 + 26251 = 26280
- 31 + 26249 = 26280
- 43 + 26237 = 26280
- 53 + 26227 = 26280
- 71 + 26209 = 26280
Showing the first eight; more decompositions exist.
