Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709564, here are decompositions:

11 + 8709553 = 8709564
37 + 8709527 = 8709564
103 + 8709461 = 8709564
181 + 8709383 = 8709564
191 + 8709373 = 8709564
251 + 8709313 = 8709564
263 + 8709301 = 8709564
293 + 8709271 = 8709564

Showing the first eight; more decompositions exist.
