Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646822, here are decompositions:

5 + 8646817 = 8646822
29 + 8646793 = 8646822
43 + 8646779 = 8646822
71 + 8646751 = 8646822
101 + 8646721 = 8646822
103 + 8646719 = 8646822
113 + 8646709 = 8646822
139 + 8646683 = 8646822

Showing the first eight; more decompositions exist.
