Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729066, here are decompositions:

7 + 8729059 = 8729066
13 + 8729053 = 8729066
79 + 8728987 = 8729066
97 + 8728969 = 8729066
103 + 8728963 = 8729066
139 + 8728927 = 8729066
163 + 8728903 = 8729066
349 + 8728717 = 8729066

Showing the first eight; more decompositions exist.
