Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40016, here are decompositions:
- 3 + 40013 = 40016
- 7 + 40009 = 40016
- 37 + 39979 = 40016
- 79 + 39937 = 40016
- 139 + 39877 = 40016
- 283 + 39733 = 40016
- 307 + 39709 = 40016
- 313 + 39703 = 40016
Showing the first eight; more decompositions exist.
