Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671938, here are decompositions:

19 + 8671919 = 8671938
31 + 8671907 = 8671938
101 + 8671837 = 8671938
127 + 8671811 = 8671938
199 + 8671739 = 8671938
227 + 8671711 = 8671938
229 + 8671709 = 8671938
241 + 8671697 = 8671938

Showing the first eight; more decompositions exist.
