Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709556, here are decompositions:

3 + 8709553 = 8709556
29 + 8709527 = 8709556
47 + 8709509 = 8709556
113 + 8709443 = 8709556
173 + 8709383 = 8709556
179 + 8709377 = 8709556
239 + 8709317 = 8709556
257 + 8709299 = 8709556

Showing the first eight; more decompositions exist.
