Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670680, here are decompositions:

13 + 8670667 = 8670680
43 + 8670637 = 8670680
61 + 8670619 = 8670680
97 + 8670583 = 8670680
127 + 8670553 = 8670680
157 + 8670523 = 8670680
181 + 8670499 = 8670680
199 + 8670481 = 8670680

Showing the first eight; more decompositions exist.
