Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997722, here are decompositions:

23 + 997699 = 997722
29 + 997693 = 997722
41 + 997681 = 997722
59 + 997663 = 997722
71 + 997651 = 997722
73 + 997649 = 997722
113 + 997609 = 997722
139 + 997583 = 997722

Showing the first eight; more decompositions exist.
