Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671328, here are decompositions:

7 + 8671321 = 8671328
37 + 8671291 = 8671328
79 + 8671249 = 8671328
97 + 8671231 = 8671328
109 + 8671219 = 8671328
151 + 8671177 = 8671328
181 + 8671147 = 8671328
229 + 8671099 = 8671328

Showing the first eight; more decompositions exist.
