Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717888, here are decompositions:

7 + 8717881 = 8717888
19 + 8717869 = 8717888
31 + 8717857 = 8717888
79 + 8717809 = 8717888
97 + 8717791 = 8717888
139 + 8717749 = 8717888
199 + 8717689 = 8717888
211 + 8717677 = 8717888

Showing the first eight; more decompositions exist.
