Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646664, here are decompositions:

83 + 8646581 = 8646664
167 + 8646497 = 8646664
263 + 8646401 = 8646664
347 + 8646317 = 8646664
431 + 8646233 = 8646664
443 + 8646221 = 8646664
557 + 8646107 = 8646664
647 + 8646017 = 8646664

Showing the first eight; more decompositions exist.
