Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728896, here are decompositions:

13 + 8728883 = 8728896
47 + 8728849 = 8728896
73 + 8728823 = 8728896
89 + 8728807 = 8728896
109 + 8728787 = 8728896
139 + 8728757 = 8728896
179 + 8728717 = 8728896
233 + 8728663 = 8728896

Showing the first eight; more decompositions exist.
