Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80858, here are decompositions:
- 79 + 80779 = 80858
- 97 + 80761 = 80858
- 109 + 80749 = 80858
- 157 + 80701 = 80858
- 181 + 80677 = 80858
- 229 + 80629 = 80858
- 331 + 80527 = 80858
- 367 + 80491 = 80858
Showing the first eight; more decompositions exist.
