Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617564, here are decompositions:

3 + 8617561 = 8617564
17 + 8617547 = 8617564
41 + 8617523 = 8617564
167 + 8617397 = 8617564
173 + 8617391 = 8617564
191 + 8617373 = 8617564
251 + 8617313 = 8617564
311 + 8617253 = 8617564

Showing the first eight; more decompositions exist.
