Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77658, here are decompositions:

11 + 77647 = 77658
17 + 77641 = 77658
37 + 77621 = 77658
41 + 77617 = 77658
47 + 77611 = 77658
67 + 77591 = 77658
71 + 77587 = 77658
89 + 77569 = 77658

Showing the first eight; more decompositions exist.
