Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710878, here are decompositions:

31 + 8710847 = 8710878
97 + 8710781 = 8710878
107 + 8710771 = 8710878
131 + 8710747 = 8710878
149 + 8710729 = 8710878
151 + 8710727 = 8710878
179 + 8710699 = 8710878
191 + 8710687 = 8710878

Showing the first eight; more decompositions exist.
