Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717980, here are decompositions:

17 + 8717963 = 8717980
41 + 8717939 = 8717980
53 + 8717927 = 8717980
71 + 8717909 = 8717980
107 + 8717873 = 8717980
113 + 8717867 = 8717980
137 + 8717843 = 8717980
197 + 8717783 = 8717980

Showing the first eight; more decompositions exist.
