Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51968, here are decompositions:

19 + 51949 = 51968
61 + 51907 = 51968
97 + 51871 = 51968
109 + 51859 = 51968
139 + 51829 = 51968
151 + 51817 = 51968
181 + 51787 = 51968
199 + 51769 = 51968

Showing the first eight; more decompositions exist.
