Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65928, here are decompositions:

7 + 65921 = 65928
29 + 65899 = 65928
47 + 65881 = 65928
61 + 65867 = 65928
89 + 65839 = 65928
97 + 65831 = 65928
101 + 65827 = 65928
139 + 65789 = 65928

Showing the first eight; more decompositions exist.
