Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717856, here are decompositions:

13 + 8717843 = 8717856
47 + 8717809 = 8717856
53 + 8717803 = 8717856
73 + 8717783 = 8717856
83 + 8717773 = 8717856
89 + 8717767 = 8717856
107 + 8717749 = 8717856
109 + 8717747 = 8717856

Showing the first eight; more decompositions exist.
