Goldbach decomposition

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.
