Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728956, here are decompositions:

13 + 8728943 = 8728956
29 + 8728927 = 8728956
53 + 8728903 = 8728956
59 + 8728897 = 8728956
73 + 8728883 = 8728956
107 + 8728849 = 8728956
149 + 8728807 = 8728956
199 + 8728757 = 8728956

Showing the first eight; more decompositions exist.
