Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642874, here are decompositions:

11 + 8642863 = 8642874
13 + 8642861 = 8642874
17 + 8642857 = 8642874
101 + 8642773 = 8642874
113 + 8642761 = 8642874
127 + 8642747 = 8642874
151 + 8642723 = 8642874
223 + 8642651 = 8642874

Showing the first eight; more decompositions exist.
