Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68458, here are decompositions:
- 11 + 68447 = 68458
- 59 + 68399 = 68458
- 107 + 68351 = 68458
- 179 + 68279 = 68458
- 197 + 68261 = 68458
- 239 + 68219 = 68458
- 251 + 68207 = 68458
- 311 + 68147 = 68458
Showing the first eight; more decompositions exist.
