Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40022, here are decompositions:
- 13 + 40009 = 40022
- 43 + 39979 = 40022
- 139 + 39883 = 40022
- 181 + 39841 = 40022
- 193 + 39829 = 40022
- 223 + 39799 = 40022
- 313 + 39709 = 40022
- 523 + 39499 = 40022
Showing the first eight; more decompositions exist.
