Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718556, here are decompositions:

17 + 8718539 = 8718556
53 + 8718503 = 8718556
137 + 8718419 = 8718556
149 + 8718407 = 8718556
179 + 8718377 = 8718556
359 + 8718197 = 8718556
443 + 8718113 = 8718556
467 + 8718089 = 8718556

Showing the first eight; more decompositions exist.
