Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617644, here are decompositions:

17 + 8617627 = 8617644
83 + 8617561 = 8617644
97 + 8617547 = 8617644
131 + 8617513 = 8617644
197 + 8617447 = 8617644
227 + 8617417 = 8617644
263 + 8617381 = 8617644
271 + 8617373 = 8617644

Showing the first eight; more decompositions exist.
