Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601638, here are decompositions:

7 + 8601631 = 8601638
127 + 8601511 = 8601638
139 + 8601499 = 8601638
181 + 8601457 = 8601638
277 + 8601361 = 8601638
307 + 8601331 = 8601638
349 + 8601289 = 8601638
541 + 8601097 = 8601638

Showing the first eight; more decompositions exist.
