Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715372, here are decompositions:

11 + 8715361 = 8715372
23 + 8715349 = 8715372
103 + 8715269 = 8715372
109 + 8715263 = 8715372
139 + 8715233 = 8715372
163 + 8715209 = 8715372
179 + 8715193 = 8715372
181 + 8715191 = 8715372

Showing the first eight; more decompositions exist.
