Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671738, here are decompositions:

17 + 8671721 = 8671738
29 + 8671709 = 8671738
41 + 8671697 = 8671738
107 + 8671631 = 8671738
149 + 8671589 = 8671738
227 + 8671511 = 8671738
239 + 8671499 = 8671738
269 + 8671469 = 8671738

Showing the first eight; more decompositions exist.
