Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671616, here are decompositions:

43 + 8671573 = 8671616
67 + 8671549 = 8671616
97 + 8671519 = 8671616
223 + 8671393 = 8671616
277 + 8671339 = 8671616
367 + 8671249 = 8671616
397 + 8671219 = 8671616
439 + 8671177 = 8671616

Showing the first eight; more decompositions exist.
