Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642964, here are decompositions:

13 + 8642951 = 8642964
17 + 8642947 = 8642964
37 + 8642927 = 8642964
53 + 8642911 = 8642964
61 + 8642903 = 8642964
67 + 8642897 = 8642964
101 + 8642863 = 8642964
103 + 8642861 = 8642964

Showing the first eight; more decompositions exist.
