Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671398, here are decompositions:

5 + 8671393 = 8671398
17 + 8671381 = 8671398
31 + 8671367 = 8671398
37 + 8671361 = 8671398
59 + 8671339 = 8671398
67 + 8671331 = 8671398
107 + 8671291 = 8671398
149 + 8671249 = 8671398

Showing the first eight; more decompositions exist.
