Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666984, here are decompositions:

31 + 8666953 = 8666984
103 + 8666881 = 8666984
211 + 8666773 = 8666984
541 + 8666443 = 8666984
661 + 8666323 = 8666984
811 + 8666173 = 8666984
967 + 8666017 = 8666984
1051 + 8665933 = 8666984

Showing the first eight; more decompositions exist.
