Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40684, here are decompositions:
- 47 + 40637 = 40684
- 101 + 40583 = 40684
- 107 + 40577 = 40684
- 191 + 40493 = 40684
- 197 + 40487 = 40684
- 251 + 40433 = 40684
- 257 + 40427 = 40684
- 401 + 40283 = 40684
Showing the first eight; more decompositions exist.
