Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51966, here are decompositions:

17 + 51949 = 51966
37 + 51929 = 51966
53 + 51913 = 51966
59 + 51907 = 51966
67 + 51899 = 51966
73 + 51893 = 51966
97 + 51869 = 51966
107 + 51859 = 51966

Showing the first eight; more decompositions exist.
