Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716920, here are decompositions:

29 + 8716891 = 8716920
31 + 8716889 = 8716920
59 + 8716861 = 8716920
67 + 8716853 = 8716920
101 + 8716819 = 8716920
103 + 8716817 = 8716920
137 + 8716783 = 8716920
151 + 8716769 = 8716920

Showing the first eight; more decompositions exist.
