Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 996642, here are decompositions:

5 + 996637 = 996642
11 + 996631 = 996642
13 + 996629 = 996642
41 + 996601 = 996642
43 + 996599 = 996642
71 + 996571 = 996642
79 + 996563 = 996642
103 + 996539 = 996642

Showing the first eight; more decompositions exist.
