Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729106, here are decompositions:

7 + 8729099 = 8729106
13 + 8729093 = 8729106
47 + 8729059 = 8729106
53 + 8729053 = 8729106
73 + 8729033 = 8729106
137 + 8728969 = 8729106
163 + 8728943 = 8729106
179 + 8728927 = 8729106

Showing the first eight; more decompositions exist.
