Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630844, here are decompositions:

7 + 8630837 = 8630844
11 + 8630833 = 8630844
23 + 8630821 = 8630844
31 + 8630813 = 8630844
73 + 8630771 = 8630844
107 + 8630737 = 8630844
181 + 8630663 = 8630844
191 + 8630653 = 8630844

Showing the first eight; more decompositions exist.
