Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715984, here are decompositions:

7 + 8715977 = 8715984
23 + 8715961 = 8715984
37 + 8715947 = 8715984
47 + 8715937 = 8715984
83 + 8715901 = 8715984
97 + 8715887 = 8715984
103 + 8715881 = 8715984
107 + 8715877 = 8715984

Showing the first eight; more decompositions exist.
