Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717886, here are decompositions:

5 + 8717881 = 8717886
13 + 8717873 = 8717886
17 + 8717869 = 8717886
19 + 8717867 = 8717886
29 + 8717857 = 8717886
43 + 8717843 = 8717886
83 + 8717803 = 8717886
103 + 8717783 = 8717886

Showing the first eight; more decompositions exist.
