Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621976, here are decompositions:

5 + 8621971 = 8621976
17 + 8621959 = 8621976
29 + 8621947 = 8621976
37 + 8621939 = 8621976
43 + 8621933 = 8621976
79 + 8621897 = 8621976
107 + 8621869 = 8621976
109 + 8621867 = 8621976

Showing the first eight; more decompositions exist.
