Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607686, here are decompositions:

13 + 8607673 = 8607686
19 + 8607667 = 8607686
103 + 8607583 = 8607686
223 + 8607463 = 8607686
277 + 8607409 = 8607686
313 + 8607373 = 8607686
379 + 8607307 = 8607686
463 + 8607223 = 8607686

Showing the first eight; more decompositions exist.
