Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621826, here are decompositions:

7 + 8621819 = 8621826
29 + 8621797 = 8621826
47 + 8621779 = 8621826
53 + 8621773 = 8621826
79 + 8621747 = 8621826
149 + 8621677 = 8621826
173 + 8621653 = 8621826
347 + 8621479 = 8621826

Showing the first eight; more decompositions exist.
