Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605664, here are decompositions:

97 + 8605567 = 8605664
103 + 8605561 = 8605664
163 + 8605501 = 8605664
367 + 8605297 = 8605664
433 + 8605231 = 8605664
607 + 8605057 = 8605664
673 + 8604991 = 8605664
751 + 8604913 = 8605664

Showing the first eight; more decompositions exist.
