Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997698, here are decompositions:

5 + 997693 = 997698
17 + 997681 = 997698
47 + 997651 = 997698
61 + 997637 = 997698
71 + 997627 = 997698
89 + 997609 = 997698
101 + 997597 = 997698
109 + 997589 = 997698

Showing the first eight; more decompositions exist.
