Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646904, here are decompositions:

5 + 8646899 = 8646904
53 + 8646851 = 8646904
83 + 8646821 = 8646904
197 + 8646707 = 8646904
401 + 8646503 = 8646904
503 + 8646401 = 8646904
587 + 8646317 = 8646904
647 + 8646257 = 8646904

Showing the first eight; more decompositions exist.
