Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715408, here are decompositions:

5 + 8715403 = 8715408
7 + 8715401 = 8715408
47 + 8715361 = 8715408
59 + 8715349 = 8715408
61 + 8715347 = 8715408
71 + 8715337 = 8715408
139 + 8715269 = 8715408
199 + 8715209 = 8715408

Showing the first eight; more decompositions exist.
