Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622018, here are decompositions:

7 + 8622011 = 8622018
11 + 8622007 = 8622018
17 + 8622001 = 8622018
29 + 8621989 = 8622018
47 + 8621971 = 8622018
59 + 8621959 = 8622018
71 + 8621947 = 8622018
79 + 8621939 = 8622018

Showing the first eight; more decompositions exist.
