Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705656, here are decompositions:

17 + 8705639 = 8705656
83 + 8705573 = 8705656
107 + 8705549 = 8705656
137 + 8705519 = 8705656
149 + 8705507 = 8705656
173 + 8705483 = 8705656
227 + 8705429 = 8705656
257 + 8705399 = 8705656

Showing the first eight; more decompositions exist.
