Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715406, here are decompositions:

3 + 8715403 = 8715406
5 + 8715401 = 8715406
23 + 8715383 = 8715406
59 + 8715347 = 8715406
83 + 8715323 = 8715406
137 + 8715269 = 8715406
173 + 8715233 = 8715406
197 + 8715209 = 8715406

Showing the first eight; more decompositions exist.
