Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691984, here are decompositions:

5 + 8691979 = 8691984
11 + 8691973 = 8691984
13 + 8691971 = 8691984
23 + 8691961 = 8691984
43 + 8691941 = 8691984
47 + 8691937 = 8691984
61 + 8691923 = 8691984
83 + 8691901 = 8691984

Showing the first eight; more decompositions exist.
