Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671682, here are decompositions:

13 + 8671669 = 8671682
43 + 8671639 = 8671682
109 + 8671573 = 8671682
163 + 8671519 = 8671682
181 + 8671501 = 8671682
211 + 8671471 = 8671682
241 + 8671441 = 8671682
433 + 8671249 = 8671682

Showing the first eight; more decompositions exist.
