Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601440, here are decompositions:

19 + 8601421 = 8601440
79 + 8601361 = 8601440
97 + 8601343 = 8601440
109 + 8601331 = 8601440
151 + 8601289 = 8601440
163 + 8601277 = 8601440
271 + 8601169 = 8601440
277 + 8601163 = 8601440

Showing the first eight; more decompositions exist.
