Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40406, here are decompositions:
- 19 + 40387 = 40406
- 193 + 40213 = 40406
- 229 + 40177 = 40406
- 277 + 40129 = 40406
- 283 + 40123 = 40406
- 307 + 40099 = 40406
- 313 + 40093 = 40406
- 367 + 40039 = 40406
Showing the first eight; more decompositions exist.
