Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729904, here are decompositions:

17 + 8729887 = 8729904
23 + 8729881 = 8729904
37 + 8729867 = 8729904
67 + 8729837 = 8729904
83 + 8729821 = 8729904
103 + 8729801 = 8729904
137 + 8729767 = 8729904
193 + 8729711 = 8729904

Showing the first eight; more decompositions exist.
