Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642958, here are decompositions:

7 + 8642951 = 8642958
11 + 8642947 = 8642958
19 + 8642939 = 8642958
31 + 8642927 = 8642958
47 + 8642911 = 8642958
61 + 8642897 = 8642958
97 + 8642861 = 8642958
101 + 8642857 = 8642958

Showing the first eight; more decompositions exist.
