Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620874, here are decompositions:

13 + 8620861 = 8620874
127 + 8620747 = 8620874
151 + 8620723 = 8620874
211 + 8620663 = 8620874
271 + 8620603 = 8620874
307 + 8620567 = 8620874
331 + 8620543 = 8620874
547 + 8620327 = 8620874

Showing the first eight; more decompositions exist.
