Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78816, here are decompositions:

7 + 78809 = 78816
13 + 78803 = 78816
19 + 78797 = 78816
29 + 78787 = 78816
37 + 78779 = 78816
79 + 78737 = 78816
103 + 78713 = 78816
109 + 78707 = 78816

Showing the first eight; more decompositions exist.
