Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715456, here are decompositions:

5 + 8715451 = 8715456
7 + 8715449 = 8715456
47 + 8715409 = 8715456
53 + 8715403 = 8715456
73 + 8715383 = 8715456
107 + 8715349 = 8715456
109 + 8715347 = 8715456
193 + 8715263 = 8715456

Showing the first eight; more decompositions exist.
