Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671568, here are decompositions:

19 + 8671549 = 8671568
67 + 8671501 = 8671568
97 + 8671471 = 8671568
127 + 8671441 = 8671568
229 + 8671339 = 8671568
277 + 8671291 = 8671568
337 + 8671231 = 8671568
349 + 8671219 = 8671568

Showing the first eight; more decompositions exist.
