Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716870, here are decompositions:

17 + 8716853 = 8716870
53 + 8716817 = 8716870
101 + 8716769 = 8716870
167 + 8716703 = 8716870
179 + 8716691 = 8716870
191 + 8716679 = 8716870
251 + 8716619 = 8716870
257 + 8716613 = 8716870

Showing the first eight; more decompositions exist.
