Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621876, here are decompositions:

7 + 8621869 = 8621876
13 + 8621863 = 8621876
19 + 8621857 = 8621876
79 + 8621797 = 8621876
97 + 8621779 = 8621876
103 + 8621773 = 8621876
127 + 8621749 = 8621876
199 + 8621677 = 8621876

Showing the first eight; more decompositions exist.
