Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40458, here are decompositions:
- 29 + 40429 = 40458
- 31 + 40427 = 40458
- 71 + 40387 = 40458
- 97 + 40361 = 40458
- 101 + 40357 = 40458
- 107 + 40351 = 40458
- 181 + 40277 = 40458
- 227 + 40231 = 40458
Showing the first eight; more decompositions exist.
