Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61858, here are decompositions:
- 101 + 61757 = 61858
- 107 + 61751 = 61858
- 191 + 61667 = 61858
- 227 + 61631 = 61858
- 311 + 61547 = 61858
- 347 + 61511 = 61858
- 389 + 61469 = 61858
- 449 + 61409 = 61858
Showing the first eight; more decompositions exist.
