Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729874, here are decompositions:

5 + 8729869 = 8729874
7 + 8729867 = 8729874
37 + 8729837 = 8729874
53 + 8729821 = 8729874
73 + 8729801 = 8729874
107 + 8729767 = 8729874
157 + 8729717 = 8729874
163 + 8729711 = 8729874

Showing the first eight; more decompositions exist.
