Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670686, here are decompositions:

7 + 8670679 = 8670686
19 + 8670667 = 8670686
67 + 8670619 = 8670686
97 + 8670589 = 8670686
103 + 8670583 = 8670686
127 + 8670559 = 8670686
163 + 8670523 = 8670686
313 + 8670373 = 8670686

Showing the first eight; more decompositions exist.
