Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77858, here are decompositions:
- 19 + 77839 = 77858
- 61 + 77797 = 77858
- 97 + 77761 = 77858
- 127 + 77731 = 77858
- 139 + 77719 = 77858
- 199 + 77659 = 77858
- 211 + 77647 = 77858
- 241 + 77617 = 77858
Showing the first eight; more decompositions exist.
