Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717880, here are decompositions:

7 + 8717873 = 8717880
11 + 8717869 = 8717880
13 + 8717867 = 8717880
19 + 8717861 = 8717880
23 + 8717857 = 8717880
37 + 8717843 = 8717880
71 + 8717809 = 8717880
89 + 8717791 = 8717880

Showing the first eight; more decompositions exist.
