Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51856, here are decompositions:

3 + 51853 = 51856
17 + 51839 = 51856
29 + 51827 = 51856
53 + 51803 = 51856
59 + 51797 = 51856
89 + 51767 = 51856
107 + 51749 = 51856
137 + 51719 = 51856

Showing the first eight; more decompositions exist.
