Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729006, here are decompositions:

19 + 8728987 = 8729006
37 + 8728969 = 8729006
43 + 8728963 = 8729006
79 + 8728927 = 8729006
103 + 8728903 = 8729006
109 + 8728897 = 8729006
157 + 8728849 = 8729006
199 + 8728807 = 8729006

Showing the first eight; more decompositions exist.
