Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997656, here are decompositions:

5 + 997651 = 997656
7 + 997649 = 997656
19 + 997637 = 997656
29 + 997627 = 997656
47 + 997609 = 997656
59 + 997597 = 997656
67 + 997589 = 997656
73 + 997583 = 997656

Showing the first eight; more decompositions exist.
