Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642968, here are decompositions:

17 + 8642951 = 8642968
29 + 8642939 = 8642968
41 + 8642927 = 8642968
71 + 8642897 = 8642968
107 + 8642861 = 8642968
149 + 8642819 = 8642968
317 + 8642651 = 8642968
401 + 8642567 = 8642968

Showing the first eight; more decompositions exist.
