Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700878, here are decompositions:

7 + 8700871 = 8700878
61 + 8700817 = 8700878
79 + 8700799 = 8700878
127 + 8700751 = 8700878
157 + 8700721 = 8700878
181 + 8700697 = 8700878
229 + 8700649 = 8700878
331 + 8700547 = 8700878

Showing the first eight; more decompositions exist.
