Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709312, here are decompositions:

11 + 8709301 = 8709312
13 + 8709299 = 8709312
23 + 8709289 = 8709312
41 + 8709271 = 8709312
83 + 8709229 = 8709312
163 + 8709149 = 8709312
173 + 8709139 = 8709312
179 + 8709133 = 8709312

Showing the first eight; more decompositions exist.
