Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729072, here are decompositions:

13 + 8729059 = 8729072
19 + 8729053 = 8729072
103 + 8728969 = 8729072
109 + 8728963 = 8729072
151 + 8728921 = 8729072
223 + 8728849 = 8729072
409 + 8728663 = 8729072
463 + 8728609 = 8729072

Showing the first eight; more decompositions exist.
