Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729844, here are decompositions:

5 + 8729839 = 8729844
7 + 8729837 = 8729844
23 + 8729821 = 8729844
43 + 8729801 = 8729844
127 + 8729717 = 8729844
163 + 8729681 = 8729844
197 + 8729647 = 8729844
223 + 8729621 = 8729844

Showing the first eight; more decompositions exist.
