Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40048, here are decompositions:
- 11 + 40037 = 40048
- 17 + 40031 = 40048
- 59 + 39989 = 40048
- 179 + 39869 = 40048
- 191 + 39857 = 40048
- 227 + 39821 = 40048
- 257 + 39791 = 40048
- 269 + 39779 = 40048
Showing the first eight; more decompositions exist.
