Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671758, here are decompositions:

19 + 8671739 = 8671758
37 + 8671721 = 8671758
47 + 8671711 = 8671758
61 + 8671697 = 8671758
89 + 8671669 = 8671758
127 + 8671631 = 8671758
239 + 8671519 = 8671758
241 + 8671517 = 8671758

Showing the first eight; more decompositions exist.
