Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705328, here are decompositions:

17 + 8705311 = 8705328
29 + 8705299 = 8705328
31 + 8705297 = 8705328
59 + 8705269 = 8705328
67 + 8705261 = 8705328
109 + 8705219 = 8705328
157 + 8705171 = 8705328
179 + 8705149 = 8705328

Showing the first eight; more decompositions exist.
