Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621994, here are decompositions:

5 + 8621989 = 8621994
11 + 8621983 = 8621994
23 + 8621971 = 8621994
47 + 8621947 = 8621994
61 + 8621933 = 8621994
67 + 8621927 = 8621994
83 + 8621911 = 8621994
97 + 8621897 = 8621994

Showing the first eight; more decompositions exist.
