Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997668, here are decompositions:

5 + 997663 = 997668
17 + 997651 = 997668
19 + 997649 = 997668
31 + 997637 = 997668
41 + 997627 = 997668
59 + 997609 = 997668
71 + 997597 = 997668
79 + 997589 = 997668

Showing the first eight; more decompositions exist.
