Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620958, here are decompositions:

7 + 8620951 = 8620958
61 + 8620897 = 8620958
97 + 8620861 = 8620958
211 + 8620747 = 8620958
271 + 8620687 = 8620958
337 + 8620621 = 8620958
631 + 8620327 = 8620958
691 + 8620267 = 8620958

Showing the first eight; more decompositions exist.
