Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729150, here are decompositions:

19 + 8729131 = 8729150
43 + 8729107 = 8729150
97 + 8729053 = 8729150
163 + 8728987 = 8729150
181 + 8728969 = 8729150
223 + 8728927 = 8729150
229 + 8728921 = 8729150
433 + 8728717 = 8729150

Showing the first eight; more decompositions exist.
