Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668920, here are decompositions:

19 + 8668901 = 8668920
23 + 8668897 = 8668920
31 + 8668889 = 8668920
47 + 8668873 = 8668920
83 + 8668837 = 8668920
89 + 8668831 = 8668920
103 + 8668817 = 8668920
107 + 8668813 = 8668920

Showing the first eight; more decompositions exist.
