Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653944, here are decompositions:

7 + 8653937 = 8653944
41 + 8653903 = 8653944
53 + 8653891 = 8653944
67 + 8653877 = 8653944
97 + 8653847 = 8653944
127 + 8653817 = 8653944
137 + 8653807 = 8653944
181 + 8653763 = 8653944

Showing the first eight; more decompositions exist.
