Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40726, here are decompositions:
- 17 + 40709 = 40726
- 29 + 40697 = 40726
- 89 + 40637 = 40726
- 149 + 40577 = 40726
- 167 + 40559 = 40726
- 197 + 40529 = 40726
- 227 + 40499 = 40726
- 233 + 40493 = 40726
Showing the first eight; more decompositions exist.
