Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669166, here are decompositions:

7 + 8669159 = 8669166
43 + 8669123 = 8669166
53 + 8669113 = 8669166
59 + 8669107 = 8669166
83 + 8669083 = 8669166
139 + 8669027 = 8669166
173 + 8668993 = 8669166
193 + 8668973 = 8669166

Showing the first eight; more decompositions exist.
