Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671726, here are decompositions:

5 + 8671721 = 8671726
17 + 8671709 = 8671726
29 + 8671697 = 8671726
137 + 8671589 = 8671726
227 + 8671499 = 8671726
257 + 8671469 = 8671726
263 + 8671463 = 8671726
269 + 8671457 = 8671726

Showing the first eight; more decompositions exist.
