Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671376, here are decompositions:

13 + 8671363 = 8671376
37 + 8671339 = 8671376
127 + 8671249 = 8671376
157 + 8671219 = 8671376
199 + 8671177 = 8671376
229 + 8671147 = 8671376
277 + 8671099 = 8671376
313 + 8671063 = 8671376

Showing the first eight; more decompositions exist.
