Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637970, here are decompositions:

17 + 8637953 = 8637970
41 + 8637929 = 8637970
101 + 8637869 = 8637970
149 + 8637821 = 8637970
179 + 8637791 = 8637970
191 + 8637779 = 8637970
269 + 8637701 = 8637970
353 + 8637617 = 8637970

Showing the first eight; more decompositions exist.
