Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77756, here are decompositions:

13 + 77743 = 77756
37 + 77719 = 77756
43 + 77713 = 77756
67 + 77689 = 77756
97 + 77659 = 77756
109 + 77647 = 77756
139 + 77617 = 77756
193 + 77563 = 77756

Showing the first eight; more decompositions exist.
