Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57864, here are decompositions:

5 + 57859 = 57864
11 + 57853 = 57864
17 + 57847 = 57864
61 + 57803 = 57864
71 + 57793 = 57864
73 + 57791 = 57864
83 + 57781 = 57864
113 + 57751 = 57864

Showing the first eight; more decompositions exist.
