Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670786, here are decompositions:

13 + 8670773 = 8670786
43 + 8670743 = 8670786
73 + 8670713 = 8670786
83 + 8670703 = 8670786
107 + 8670679 = 8670786
149 + 8670637 = 8670786
167 + 8670619 = 8670786
197 + 8670589 = 8670786

Showing the first eight; more decompositions exist.
