Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729064, here are decompositions:

5 + 8729059 = 8729064
7 + 8729057 = 8729064
11 + 8729053 = 8729064
13 + 8729051 = 8729064
31 + 8729033 = 8729064
101 + 8728963 = 8729064
137 + 8728927 = 8729064
163 + 8728901 = 8729064

Showing the first eight; more decompositions exist.
