Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671384, here are decompositions:

3 + 8671381 = 8671384
17 + 8671367 = 8671384
23 + 8671361 = 8671384
53 + 8671331 = 8671384
191 + 8671193 = 8671384
233 + 8671151 = 8671384
251 + 8671133 = 8671384
257 + 8671127 = 8671384

Showing the first eight; more decompositions exist.
