Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676878, here are decompositions:

31 + 8676847 = 8676878
79 + 8676799 = 8676878
97 + 8676781 = 8676878
109 + 8676769 = 8676878
127 + 8676751 = 8676878
157 + 8676721 = 8676878
277 + 8676601 = 8676878
337 + 8676541 = 8676878

Showing the first eight; more decompositions exist.
