Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621894, here are decompositions:

31 + 8621863 = 8621894
37 + 8621857 = 8621894
67 + 8621827 = 8621894
97 + 8621797 = 8621894
241 + 8621653 = 8621894
271 + 8621623 = 8621894
277 + 8621617 = 8621894
313 + 8621581 = 8621894

Showing the first eight; more decompositions exist.
