Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729126, here are decompositions:

19 + 8729107 = 8729126
67 + 8729059 = 8729126
73 + 8729053 = 8729126
139 + 8728987 = 8729126
157 + 8728969 = 8729126
163 + 8728963 = 8729126
199 + 8728927 = 8729126
223 + 8728903 = 8729126

Showing the first eight; more decompositions exist.
