Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717816, here are decompositions:

7 + 8717809 = 8717816
13 + 8717803 = 8717816
43 + 8717773 = 8717816
67 + 8717749 = 8717816
73 + 8717743 = 8717816
127 + 8717689 = 8717816
139 + 8717677 = 8717816
193 + 8717623 = 8717816

Showing the first eight; more decompositions exist.
