Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671680, here are decompositions:

11 + 8671669 = 8671680
41 + 8671639 = 8671680
47 + 8671633 = 8671680
97 + 8671583 = 8671680
107 + 8671573 = 8671680
131 + 8671549 = 8671680
163 + 8671517 = 8671680
179 + 8671501 = 8671680

Showing the first eight; more decompositions exist.
