Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660066, here are decompositions:

13 + 8660053 = 8660066
67 + 8659999 = 8660066
109 + 8659957 = 8660066
127 + 8659939 = 8660066
139 + 8659927 = 8660066
157 + 8659909 = 8660066
193 + 8659873 = 8660066
199 + 8659867 = 8660066

Showing the first eight; more decompositions exist.
