Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648844, here are decompositions:

5 + 8648839 = 8648844
7 + 8648837 = 8648844
11 + 8648833 = 8648844
13 + 8648831 = 8648844
31 + 8648813 = 8648844
47 + 8648797 = 8648844
53 + 8648791 = 8648844
97 + 8648747 = 8648844

Showing the first eight; more decompositions exist.
