Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77610, here are decompositions:

19 + 77591 = 77610
23 + 77587 = 77610
37 + 77573 = 77610
41 + 77569 = 77610
47 + 77563 = 77610
53 + 77557 = 77610
59 + 77551 = 77610
61 + 77549 = 77610

Showing the first eight; more decompositions exist.
