Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657944, here are decompositions:

11 + 8657933 = 8657944
17 + 8657927 = 8657944
41 + 8657903 = 8657944
173 + 8657771 = 8657944
257 + 8657687 = 8657944
263 + 8657681 = 8657944
293 + 8657651 = 8657944
311 + 8657633 = 8657944

Showing the first eight; more decompositions exist.
