Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729908, here are decompositions:

41 + 8729867 = 8729908
59 + 8729849 = 8729908
71 + 8729837 = 8729908
107 + 8729801 = 8729908
179 + 8729729 = 8729908
191 + 8729717 = 8729908
197 + 8729711 = 8729908
227 + 8729681 = 8729908

Showing the first eight; more decompositions exist.
