Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77860, here are decompositions:

11 + 77849 = 77860
47 + 77813 = 77860
59 + 77801 = 77860
113 + 77747 = 77860
137 + 77723 = 77860
149 + 77711 = 77860
173 + 77687 = 77860
179 + 77681 = 77860

Showing the first eight; more decompositions exist.
