Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671340, here are decompositions:

19 + 8671321 = 8671340
109 + 8671231 = 8671340
163 + 8671177 = 8671340
193 + 8671147 = 8671340
241 + 8671099 = 8671340
277 + 8671063 = 8671340
283 + 8671057 = 8671340
331 + 8671009 = 8671340

Showing the first eight; more decompositions exist.
