Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642916, here are decompositions:

5 + 8642911 = 8642916
13 + 8642903 = 8642916
19 + 8642897 = 8642916
53 + 8642863 = 8642916
59 + 8642857 = 8642916
67 + 8642849 = 8642916
97 + 8642819 = 8642916
193 + 8642723 = 8642916

Showing the first eight; more decompositions exist.
