Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997680, here are decompositions:

17 + 997663 = 997680
29 + 997651 = 997680
31 + 997649 = 997680
43 + 997637 = 997680
53 + 997627 = 997680
71 + 997609 = 997680
83 + 997597 = 997680
97 + 997583 = 997680

Showing the first eight; more decompositions exist.
