Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717904, here are decompositions:

23 + 8717881 = 8717904
31 + 8717873 = 8717904
37 + 8717867 = 8717904
43 + 8717861 = 8717904
47 + 8717857 = 8717904
61 + 8717843 = 8717904
101 + 8717803 = 8717904
113 + 8717791 = 8717904

Showing the first eight; more decompositions exist.
