Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720958, here are decompositions:

5 + 8720953 = 8720958
11 + 8720947 = 8720958
17 + 8720941 = 8720958
47 + 8720911 = 8720958
67 + 8720891 = 8720958
139 + 8720819 = 8720958
149 + 8720809 = 8720958
151 + 8720807 = 8720958

Showing the first eight; more decompositions exist.
