Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729070, here are decompositions:

11 + 8729059 = 8729070
13 + 8729057 = 8729070
17 + 8729053 = 8729070
19 + 8729051 = 8729070
37 + 8729033 = 8729070
83 + 8728987 = 8729070
101 + 8728969 = 8729070
107 + 8728963 = 8729070

Showing the first eight; more decompositions exist.
