Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628970, here are decompositions:

3 + 8628967 = 8628970
47 + 8628923 = 8628970
71 + 8628899 = 8628970
113 + 8628857 = 8628970
179 + 8628791 = 8628970
191 + 8628779 = 8628970
197 + 8628773 = 8628970
293 + 8628677 = 8628970

Showing the first eight; more decompositions exist.
