Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77666, here are decompositions:

7 + 77659 = 77666
19 + 77647 = 77666
79 + 77587 = 77666
97 + 77569 = 77666
103 + 77563 = 77666
109 + 77557 = 77666
139 + 77527 = 77666
157 + 77509 = 77666

Showing the first eight; more decompositions exist.
