Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661984, here are decompositions:

7 + 8661977 = 8661984
31 + 8661953 = 8661984
41 + 8661943 = 8661984
43 + 8661941 = 8661984
83 + 8661901 = 8661984
101 + 8661883 = 8661984
103 + 8661881 = 8661984
113 + 8661871 = 8661984

Showing the first eight; more decompositions exist.
