Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601664, here are decompositions:

11 + 8601653 = 8601664
17 + 8601647 = 8601664
23 + 8601641 = 8601664
83 + 8601581 = 8601664
107 + 8601557 = 8601664
173 + 8601491 = 8601664
263 + 8601401 = 8601664
431 + 8601233 = 8601664

Showing the first eight; more decompositions exist.
