Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635878, here are decompositions:

11 + 8635867 = 8635878
29 + 8635849 = 8635878
61 + 8635817 = 8635878
67 + 8635811 = 8635878
101 + 8635777 = 8635878
149 + 8635729 = 8635878
179 + 8635699 = 8635878
191 + 8635687 = 8635878

Showing the first eight; more decompositions exist.
