Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621996, here are decompositions:

7 + 8621989 = 8621996
13 + 8621983 = 8621996
37 + 8621959 = 8621996
127 + 8621869 = 8621996
139 + 8621857 = 8621996
199 + 8621797 = 8621996
223 + 8621773 = 8621996
373 + 8621623 = 8621996

Showing the first eight; more decompositions exist.
