Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670870, here are decompositions:

7 + 8670863 = 8670870
59 + 8670811 = 8670870
79 + 8670791 = 8670870
97 + 8670773 = 8670870
127 + 8670743 = 8670870
157 + 8670713 = 8670870
167 + 8670703 = 8670870
191 + 8670679 = 8670870

Showing the first eight; more decompositions exist.
