Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77710, here are decompositions:

11 + 77699 = 77710
23 + 77687 = 77710
29 + 77681 = 77710
89 + 77621 = 77710
137 + 77573 = 77710
167 + 77543 = 77710
197 + 77513 = 77710
233 + 77477 = 77710

Showing the first eight; more decompositions exist.
