Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717028, here are decompositions:

7 + 8717021 = 8717028
17 + 8717011 = 8717028
29 + 8716999 = 8717028
31 + 8716997 = 8717028
71 + 8716957 = 8717028
109 + 8716919 = 8717028
137 + 8716891 = 8717028
139 + 8716889 = 8717028

Showing the first eight; more decompositions exist.
