Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616164, here are decompositions:

13 + 8616151 = 8616164
127 + 8616037 = 8616164
181 + 8615983 = 8616164
223 + 8615941 = 8616164
283 + 8615881 = 8616164
331 + 8615833 = 8616164
373 + 8615791 = 8616164
397 + 8615767 = 8616164

Showing the first eight; more decompositions exist.
