Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77728, here are decompositions:

5 + 77723 = 77728
17 + 77711 = 77728
29 + 77699 = 77728
41 + 77687 = 77728
47 + 77681 = 77728
107 + 77621 = 77728
137 + 77591 = 77728
179 + 77549 = 77728

Showing the first eight; more decompositions exist.
