Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620944, here are decompositions:

47 + 8620897 = 8620944
71 + 8620873 = 8620944
83 + 8620861 = 8620944
97 + 8620847 = 8620944
103 + 8620841 = 8620944
197 + 8620747 = 8620944
223 + 8620721 = 8620944
257 + 8620687 = 8620944

Showing the first eight; more decompositions exist.
