Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621694, here are decompositions:

13 + 8621681 = 8621694
17 + 8621677 = 8621694
41 + 8621653 = 8621694
71 + 8621623 = 8621694
113 + 8621581 = 8621694
227 + 8621467 = 8621694
241 + 8621453 = 8621694
251 + 8621443 = 8621694

Showing the first eight; more decompositions exist.
