Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607644, here are decompositions:

7 + 8607637 = 8607644
13 + 8607631 = 8607644
43 + 8607601 = 8607644
61 + 8607583 = 8607644
163 + 8607481 = 8607644
181 + 8607463 = 8607644
211 + 8607433 = 8607644
271 + 8607373 = 8607644

Showing the first eight; more decompositions exist.
