Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56280, here are decompositions:
- 11 + 56269 = 56280
- 13 + 56267 = 56280
- 17 + 56263 = 56280
- 31 + 56249 = 56280
- 41 + 56239 = 56280
- 43 + 56237 = 56280
- 71 + 56209 = 56280
- 73 + 56207 = 56280
Showing the first eight; more decompositions exist.
