Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671298, here are decompositions:

7 + 8671291 = 8671298
67 + 8671231 = 8671298
79 + 8671219 = 8671298
151 + 8671147 = 8671298
199 + 8671099 = 8671298
241 + 8671057 = 8671298
379 + 8670919 = 8671298
487 + 8670811 = 8671298

Showing the first eight; more decompositions exist.
