Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719564, here are decompositions:

23 + 8719541 = 8719564
173 + 8719391 = 8719564
197 + 8719367 = 8719564
257 + 8719307 = 8719564
263 + 8719301 = 8719564
311 + 8719253 = 8719564
353 + 8719211 = 8719564
401 + 8719163 = 8719564

Showing the first eight; more decompositions exist.
