Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670970, here are decompositions:

23 + 8670947 = 8670970
29 + 8670941 = 8670970
83 + 8670887 = 8670970
101 + 8670869 = 8670970
107 + 8670863 = 8670970
179 + 8670791 = 8670970
197 + 8670773 = 8670970
227 + 8670743 = 8670970

Showing the first eight; more decompositions exist.
