Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663878, here are decompositions:

17 + 8663861 = 8663878
59 + 8663819 = 8663878
71 + 8663807 = 8663878
101 + 8663777 = 8663878
137 + 8663741 = 8663878
191 + 8663687 = 8663878
257 + 8663621 = 8663878
269 + 8663609 = 8663878

Showing the first eight; more decompositions exist.
