Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616188, here are decompositions:

19 + 8616169 = 8616188
37 + 8616151 = 8616188
151 + 8616037 = 8616188
199 + 8615989 = 8616188
271 + 8615917 = 8616188
307 + 8615881 = 8616188
379 + 8615809 = 8616188
397 + 8615791 = 8616188

Showing the first eight; more decompositions exist.
