Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644038, here are decompositions:

19 + 8644019 = 8644038
41 + 8643997 = 8644038
47 + 8643991 = 8644038
79 + 8643959 = 8644038
97 + 8643941 = 8644038
149 + 8643889 = 8644038
199 + 8643839 = 8644038
241 + 8643797 = 8644038

Showing the first eight; more decompositions exist.
