Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656944, here are decompositions:

5 + 8656939 = 8656944
11 + 8656933 = 8656944
41 + 8656903 = 8656944
47 + 8656897 = 8656944
53 + 8656891 = 8656944
73 + 8656871 = 8656944
97 + 8656847 = 8656944
113 + 8656831 = 8656944

Showing the first eight; more decompositions exist.
