Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006650, here are decompositions:

13 + 1006637 = 1006650
17 + 1006633 = 1006650
37 + 1006613 = 1006650
41 + 1006609 = 1006650
61 + 1006589 = 1006650
67 + 1006583 = 1006650
103 + 1006547 = 1006650
107 + 1006543 = 1006650

Showing the first eight; more decompositions exist.
