Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666006, here are decompositions:

7 + 8665999 = 8666006
67 + 8665939 = 8666006
73 + 8665933 = 8666006
109 + 8665897 = 8666006
157 + 8665849 = 8666006
229 + 8665777 = 8666006
373 + 8665633 = 8666006
439 + 8665567 = 8666006

Showing the first eight; more decompositions exist.
