Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643996, here are decompositions:

5 + 8643991 = 8643996
37 + 8643959 = 8643996
43 + 8643953 = 8643996
73 + 8643923 = 8643996
103 + 8643893 = 8643996
107 + 8643889 = 8643996
157 + 8643839 = 8643996
199 + 8643797 = 8643996

Showing the first eight; more decompositions exist.
