Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006620, here are decompositions:

7 + 1006613 = 1006620
11 + 1006609 = 1006620
31 + 1006589 = 1006620
37 + 1006583 = 1006620
61 + 1006559 = 1006620
73 + 1006547 = 1006620
89 + 1006531 = 1006620
107 + 1006513 = 1006620

Showing the first eight; more decompositions exist.
