Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672540, here are decompositions:

13 + 8672527 = 8672540
31 + 8672509 = 8672540
193 + 8672347 = 8672540
277 + 8672263 = 8672540
337 + 8672203 = 8672540
379 + 8672161 = 8672540
439 + 8672101 = 8672540
829 + 8671711 = 8672540

Showing the first eight; more decompositions exist.
