Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729010, here are decompositions:

23 + 8728987 = 8729010
41 + 8728969 = 8729010
47 + 8728963 = 8729010
67 + 8728943 = 8729010
83 + 8728927 = 8729010
89 + 8728921 = 8729010
107 + 8728903 = 8729010
109 + 8728901 = 8729010

Showing the first eight; more decompositions exist.
