Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997686, here are decompositions:

5 + 997681 = 997686
23 + 997663 = 997686
37 + 997649 = 997686
59 + 997627 = 997686
89 + 997597 = 997686
97 + 997589 = 997686
103 + 997583 = 997686
113 + 997573 = 997686

Showing the first eight; more decompositions exist.
