Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17458, here are decompositions:
- 41 + 17417 = 17458
- 71 + 17387 = 17458
- 107 + 17351 = 17458
- 131 + 17327 = 17458
- 137 + 17321 = 17458
- 167 + 17291 = 17458
- 227 + 17231 = 17458
- 251 + 17207 = 17458
Showing the first eight; more decompositions exist.
