Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607428, here are decompositions:

19 + 8607409 = 8607428
31 + 8607397 = 8607428
157 + 8607271 = 8607428
211 + 8607217 = 8607428
367 + 8607061 = 8607428
499 + 8606929 = 8607428
601 + 8606827 = 8607428
631 + 8606797 = 8607428

Showing the first eight; more decompositions exist.
