Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642910, here are decompositions:

7 + 8642903 = 8642910
13 + 8642897 = 8642910
47 + 8642863 = 8642910
53 + 8642857 = 8642910
61 + 8642849 = 8642910
71 + 8642839 = 8642910
137 + 8642773 = 8642910
149 + 8642761 = 8642910

Showing the first eight; more decompositions exist.
