Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728854, here are decompositions:

5 + 8728849 = 8728854
31 + 8728823 = 8728854
47 + 8728807 = 8728854
67 + 8728787 = 8728854
97 + 8728757 = 8728854
137 + 8728717 = 8728854
163 + 8728691 = 8728854
191 + 8728663 = 8728854

Showing the first eight; more decompositions exist.
