Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707878, here are decompositions:

5 + 8707873 = 8707878
17 + 8707861 = 8707878
37 + 8707841 = 8707878
41 + 8707837 = 8707878
61 + 8707817 = 8707878
97 + 8707781 = 8707878
131 + 8707747 = 8707878
167 + 8707711 = 8707878

Showing the first eight; more decompositions exist.
