Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40540, here are decompositions:
- 11 + 40529 = 40540
- 41 + 40499 = 40540
- 47 + 40493 = 40540
- 53 + 40487 = 40540
- 107 + 40433 = 40540
- 113 + 40427 = 40540
- 179 + 40361 = 40540
- 197 + 40343 = 40540
Showing the first eight; more decompositions exist.
