Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705266, here are decompositions:

5 + 8705261 = 8705266
29 + 8705237 = 8705266
47 + 8705219 = 8705266
83 + 8705183 = 8705266
107 + 8705159 = 8705266
173 + 8705093 = 8705266
179 + 8705087 = 8705266
197 + 8705069 = 8705266

Showing the first eight; more decompositions exist.
