Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715378, here are decompositions:

17 + 8715361 = 8715378
29 + 8715349 = 8715378
31 + 8715347 = 8715378
41 + 8715337 = 8715378
109 + 8715269 = 8715378
197 + 8715181 = 8715378
227 + 8715151 = 8715378
271 + 8715107 = 8715378

Showing the first eight; more decompositions exist.
