Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660004, here are decompositions:

5 + 8659999 = 8660004
7 + 8659997 = 8660004
47 + 8659957 = 8660004
83 + 8659921 = 8660004
131 + 8659873 = 8660004
137 + 8659867 = 8660004
167 + 8659837 = 8660004
193 + 8659811 = 8660004

Showing the first eight; more decompositions exist.
