Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671660, here are decompositions:

29 + 8671631 = 8671660
71 + 8671589 = 8671660
149 + 8671511 = 8671660
191 + 8671469 = 8671660
197 + 8671463 = 8671660
233 + 8671427 = 8671660
251 + 8671409 = 8671660
293 + 8671367 = 8671660

Showing the first eight; more decompositions exist.
