Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715164, here are decompositions:

13 + 8715151 = 8715164
61 + 8715103 = 8715164
151 + 8715013 = 8715164
181 + 8714983 = 8715164
223 + 8714941 = 8715164
307 + 8714857 = 8715164
421 + 8714743 = 8715164
433 + 8714731 = 8715164

Showing the first eight; more decompositions exist.
