Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673878, here are decompositions:

61 + 8673817 = 8673878
97 + 8673781 = 8673878
151 + 8673727 = 8673878
277 + 8673601 = 8673878
307 + 8673571 = 8673878
331 + 8673547 = 8673878
379 + 8673499 = 8673878
457 + 8673421 = 8673878

Showing the first eight; more decompositions exist.
