Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642994, here are decompositions:

5 + 8642989 = 8642994
43 + 8642951 = 8642994
47 + 8642947 = 8642994
67 + 8642927 = 8642994
83 + 8642911 = 8642994
97 + 8642897 = 8642994
131 + 8642863 = 8642994
137 + 8642857 = 8642994

Showing the first eight; more decompositions exist.
