Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671286, here are decompositions:

37 + 8671249 = 8671286
67 + 8671219 = 8671286
109 + 8671177 = 8671286
139 + 8671147 = 8671286
223 + 8671063 = 8671286
229 + 8671057 = 8671286
277 + 8671009 = 8671286
367 + 8670919 = 8671286

Showing the first eight; more decompositions exist.
