Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601680, here are decompositions:

13 + 8601667 = 8601680
181 + 8601499 = 8601680
223 + 8601457 = 8601680
337 + 8601343 = 8601680
349 + 8601331 = 8601680
523 + 8601157 = 8601680
643 + 8601037 = 8601680
709 + 8600971 = 8601680

Showing the first eight; more decompositions exist.
