Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621066, here are decompositions:

19 + 8621047 = 8621066
73 + 8620993 = 8621066
193 + 8620873 = 8621066
379 + 8620687 = 8621066
463 + 8620603 = 8621066
499 + 8620567 = 8621066
523 + 8620543 = 8621066
673 + 8620393 = 8621066

Showing the first eight; more decompositions exist.
