Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642944, here are decompositions:

5 + 8642939 = 8642944
17 + 8642927 = 8642944
41 + 8642903 = 8642944
47 + 8642897 = 8642944
83 + 8642861 = 8642944
197 + 8642747 = 8642944
293 + 8642651 = 8642944
311 + 8642633 = 8642944

Showing the first eight; more decompositions exist.
