Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646970, here are decompositions:

23 + 8646947 = 8646970
41 + 8646929 = 8646970
71 + 8646899 = 8646970
149 + 8646821 = 8646970
191 + 8646779 = 8646970
251 + 8646719 = 8646970
263 + 8646707 = 8646970
389 + 8646581 = 8646970

Showing the first eight; more decompositions exist.
