Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642016, here are decompositions:

13 + 8642003 = 8642016
29 + 8641987 = 8642016
59 + 8641957 = 8642016
67 + 8641949 = 8642016
107 + 8641909 = 8642016
197 + 8641819 = 8642016
199 + 8641817 = 8642016
233 + 8641783 = 8642016

Showing the first eight; more decompositions exist.
