Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625018, here are decompositions:

5 + 8625013 = 8625018
7 + 8625011 = 8625018
11 + 8625007 = 8625018
19 + 8624999 = 8625018
37 + 8624981 = 8625018
89 + 8624929 = 8625018
97 + 8624921 = 8625018
131 + 8624887 = 8625018

Showing the first eight; more decompositions exist.
