Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77708, here are decompositions:

19 + 77689 = 77708
61 + 77647 = 77708
67 + 77641 = 77708
97 + 77611 = 77708
139 + 77569 = 77708
151 + 77557 = 77708
157 + 77551 = 77708
181 + 77527 = 77708

Showing the first eight; more decompositions exist.
