Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621026, here are decompositions:

17 + 8621009 = 8621026
53 + 8620973 = 8621026
83 + 8620943 = 8621026
179 + 8620847 = 8621026
269 + 8620757 = 8621026
353 + 8620673 = 8621026
389 + 8620637 = 8621026
677 + 8620349 = 8621026

Showing the first eight; more decompositions exist.
