Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671268, here are decompositions:

19 + 8671249 = 8671268
37 + 8671231 = 8671268
211 + 8671057 = 8671268
271 + 8670997 = 8671268
349 + 8670919 = 8671268
457 + 8670811 = 8671268
601 + 8670667 = 8671268
631 + 8670637 = 8671268

Showing the first eight; more decompositions exist.
