Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671678, here are decompositions:

47 + 8671631 = 8671678
89 + 8671589 = 8671678
167 + 8671511 = 8671678
179 + 8671499 = 8671678
251 + 8671427 = 8671678
269 + 8671409 = 8671678
311 + 8671367 = 8671678
317 + 8671361 = 8671678

Showing the first eight; more decompositions exist.
