Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85858, here are decompositions:
- 5 + 85853 = 85858
- 11 + 85847 = 85858
- 29 + 85829 = 85858
- 41 + 85817 = 85858
- 107 + 85751 = 85858
- 167 + 85691 = 85858
- 191 + 85667 = 85858
- 197 + 85661 = 85858
Showing the first eight; more decompositions exist.
