Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729892, here are decompositions:

5 + 8729887 = 8729892
11 + 8729881 = 8729892
23 + 8729869 = 8729892
43 + 8729849 = 8729892
53 + 8729839 = 8729892
71 + 8729821 = 8729892
163 + 8729729 = 8729892
181 + 8729711 = 8729892

Showing the first eight; more decompositions exist.
