Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40654, here are decompositions:
- 17 + 40637 = 40654
- 71 + 40583 = 40654
- 167 + 40487 = 40654
- 227 + 40427 = 40654
- 293 + 40361 = 40654
- 311 + 40343 = 40654
- 401 + 40253 = 40654
- 461 + 40193 = 40654
Showing the first eight; more decompositions exist.
