Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51864, here are decompositions:

5 + 51859 = 51864
11 + 51853 = 51864
37 + 51827 = 51864
47 + 51817 = 51864
61 + 51803 = 51864
67 + 51797 = 51864
97 + 51767 = 51864
151 + 51713 = 51864

Showing the first eight; more decompositions exist.
