Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77688, here are decompositions:

7 + 77681 = 77688
29 + 77659 = 77688
41 + 77647 = 77688
47 + 77641 = 77688
67 + 77621 = 77688
71 + 77617 = 77688
97 + 77591 = 77688
101 + 77587 = 77688

Showing the first eight; more decompositions exist.
