Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671216, here are decompositions:

23 + 8671193 = 8671216
83 + 8671133 = 8671216
89 + 8671127 = 8671216
149 + 8671067 = 8671216
227 + 8670989 = 8671216
269 + 8670947 = 8671216
347 + 8670869 = 8671216
353 + 8670863 = 8671216

Showing the first eight; more decompositions exist.
