Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666202, here are decompositions:

19 + 8666183 = 8666202
29 + 8666173 = 8666202
43 + 8666159 = 8666202
109 + 8666093 = 8666202
151 + 8666051 = 8666202
179 + 8666023 = 8666202
211 + 8665991 = 8666202
229 + 8665973 = 8666202

Showing the first eight; more decompositions exist.
