Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712166, here are decompositions:

3 + 8712163 = 8712166
17 + 8712149 = 8712166
53 + 8712113 = 8712166
107 + 8712059 = 8712166
137 + 8712029 = 8712166
149 + 8712017 = 8712166
179 + 8711987 = 8712166
233 + 8711933 = 8712166

Showing the first eight; more decompositions exist.
