Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57856, here are decompositions:
- 3 + 57853 = 57856
- 17 + 57839 = 57856
- 47 + 57809 = 57856
- 53 + 57803 = 57856
- 83 + 57773 = 57856
- 137 + 57719 = 57856
- 167 + 57689 = 57856
- 263 + 57593 = 57856
Showing the first eight; more decompositions exist.
