Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620964, here are decompositions:

13 + 8620951 = 8620964
67 + 8620897 = 8620964
103 + 8620861 = 8620964
241 + 8620723 = 8620964
277 + 8620687 = 8620964
397 + 8620567 = 8620964
421 + 8620543 = 8620964
571 + 8620393 = 8620964

Showing the first eight; more decompositions exist.
