Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601720, here are decompositions:

13 + 8601707 = 8601720
31 + 8601689 = 8601720
37 + 8601683 = 8601720
53 + 8601667 = 8601720
67 + 8601653 = 8601720
73 + 8601647 = 8601720
79 + 8601641 = 8601720
89 + 8601631 = 8601720

Showing the first eight; more decompositions exist.
