Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666004, here are decompositions:

5 + 8665999 = 8666004
13 + 8665991 = 8666004
31 + 8665973 = 8666004
37 + 8665967 = 8666004
71 + 8665933 = 8666004
73 + 8665931 = 8666004
107 + 8665897 = 8666004
131 + 8665873 = 8666004

Showing the first eight; more decompositions exist.
