Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715432, here are decompositions:

23 + 8715409 = 8715432
29 + 8715403 = 8715432
31 + 8715401 = 8715432
71 + 8715361 = 8715432
83 + 8715349 = 8715432
109 + 8715323 = 8715432
163 + 8715269 = 8715432
199 + 8715233 = 8715432

Showing the first eight; more decompositions exist.
