Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729108, here are decompositions:

139 + 8728969 = 8729108
181 + 8728927 = 8729108
211 + 8728897 = 8729108
397 + 8728711 = 8729108
499 + 8728609 = 8729108
727 + 8728381 = 8729108
1171 + 8727937 = 8729108
1201 + 8727907 = 8729108

Showing the first eight; more decompositions exist.
