Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997724, here are decompositions:

31 + 997693 = 997724
43 + 997681 = 997724
61 + 997663 = 997724
73 + 997651 = 997724
97 + 997627 = 997724
127 + 997597 = 997724
151 + 997573 = 997724
271 + 997453 = 997724

Showing the first eight; more decompositions exist.
