Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705256, here are decompositions:

19 + 8705237 = 8705256
37 + 8705219 = 8705256
73 + 8705183 = 8705256
89 + 8705167 = 8705256
97 + 8705159 = 8705256
107 + 8705149 = 8705256
163 + 8705093 = 8705256
179 + 8705077 = 8705256

Showing the first eight; more decompositions exist.
