Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642970, here are decompositions:

19 + 8642951 = 8642970
23 + 8642947 = 8642970
31 + 8642939 = 8642970
43 + 8642927 = 8642970
59 + 8642911 = 8642970
67 + 8642903 = 8642970
73 + 8642897 = 8642970
107 + 8642863 = 8642970

Showing the first eight; more decompositions exist.
