Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659878, here are decompositions:

5 + 8659873 = 8659878
11 + 8659867 = 8659878
41 + 8659837 = 8659878
67 + 8659811 = 8659878
109 + 8659769 = 8659878
131 + 8659747 = 8659878
137 + 8659741 = 8659878
167 + 8659711 = 8659878

Showing the first eight; more decompositions exist.
