Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607398, here are decompositions:

127 + 8607271 = 8607398
157 + 8607241 = 8607398
181 + 8607217 = 8607398
337 + 8607061 = 8607398
439 + 8606959 = 8607398
487 + 8606911 = 8607398
571 + 8606827 = 8607398
601 + 8606797 = 8607398

Showing the first eight; more decompositions exist.
