Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715520, here are decompositions:

71 + 8715449 = 8715520
89 + 8715431 = 8715520
137 + 8715383 = 8715520
173 + 8715347 = 8715520
197 + 8715323 = 8715520
251 + 8715269 = 8715520
257 + 8715263 = 8715520
311 + 8715209 = 8715520

Showing the first eight; more decompositions exist.
