Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671386, here are decompositions:

5 + 8671381 = 8671386
19 + 8671367 = 8671386
23 + 8671363 = 8671386
47 + 8671339 = 8671386
79 + 8671307 = 8671386
137 + 8671249 = 8671386
167 + 8671219 = 8671386
193 + 8671193 = 8671386

Showing the first eight; more decompositions exist.
