Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601656, here are decompositions:

3 + 8601653 = 8601656
157 + 8601499 = 8601656
199 + 8601457 = 8601656
313 + 8601343 = 8601656
367 + 8601289 = 8601656
379 + 8601277 = 8601656
487 + 8601169 = 8601656
499 + 8601157 = 8601656

Showing the first eight; more decompositions exist.
