Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709512, here are decompositions:

3 + 8709509 = 8709512
43 + 8709469 = 8709512
139 + 8709373 = 8709512
151 + 8709361 = 8709512
199 + 8709313 = 8709512
211 + 8709301 = 8709512
223 + 8709289 = 8709512
241 + 8709271 = 8709512

Showing the first eight; more decompositions exist.
