Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621006, here are decompositions:

13 + 8620993 = 8621006
109 + 8620897 = 8621006
283 + 8620723 = 8621006
367 + 8620639 = 8621006
439 + 8620567 = 8621006
463 + 8620543 = 8621006
577 + 8620429 = 8621006
613 + 8620393 = 8621006

Showing the first eight; more decompositions exist.
