Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77768, here are decompositions:

7 + 77761 = 77768
37 + 77731 = 77768
79 + 77689 = 77768
109 + 77659 = 77768
127 + 77641 = 77768
151 + 77617 = 77768
157 + 77611 = 77768
181 + 77587 = 77768

Showing the first eight; more decompositions exist.
