Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729862, here are decompositions:

13 + 8729849 = 8729862
23 + 8729839 = 8729862
41 + 8729821 = 8729862
61 + 8729801 = 8729862
151 + 8729711 = 8729862
173 + 8729689 = 8729862
181 + 8729681 = 8729862
233 + 8729629 = 8729862

Showing the first eight; more decompositions exist.
