Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677878, here are decompositions:

31 + 8677847 = 8677878
37 + 8677841 = 8677878
107 + 8677771 = 8677878
151 + 8677727 = 8677878
197 + 8677681 = 8677878
227 + 8677651 = 8677878
271 + 8677607 = 8677878
367 + 8677511 = 8677878

Showing the first eight; more decompositions exist.
