Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729838, here are decompositions:

17 + 8729821 = 8729838
37 + 8729801 = 8729838
71 + 8729767 = 8729838
109 + 8729729 = 8729838
127 + 8729711 = 8729838
149 + 8729689 = 8729838
157 + 8729681 = 8729838
179 + 8729659 = 8729838

Showing the first eight; more decompositions exist.
