Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006642, here are decompositions:

5 + 1006637 = 1006642
29 + 1006613 = 1006642
53 + 1006589 = 1006642
59 + 1006583 = 1006642
83 + 1006559 = 1006642
149 + 1006493 = 1006642
173 + 1006469 = 1006642
179 + 1006463 = 1006642

Showing the first eight; more decompositions exist.
