Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709568, here are decompositions:

5 + 8709563 = 8709568
41 + 8709527 = 8709568
59 + 8709509 = 8709568
107 + 8709461 = 8709568
137 + 8709431 = 8709568
191 + 8709377 = 8709568
251 + 8709317 = 8709568
269 + 8709299 = 8709568

Showing the first eight; more decompositions exist.
