Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616170, here are decompositions:

19 + 8616151 = 8616170
127 + 8616043 = 8616170
151 + 8616019 = 8616170
181 + 8615989 = 8616170
229 + 8615941 = 8616170
337 + 8615833 = 8616170
379 + 8615791 = 8616170
421 + 8615749 = 8616170

Showing the first eight; more decompositions exist.
