Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997790, here are decompositions:

7 + 997783 = 997790
97 + 997693 = 997790
109 + 997681 = 997790
127 + 997663 = 997790
139 + 997651 = 997790
163 + 997627 = 997790
181 + 997609 = 997790
193 + 997597 = 997790

Showing the first eight; more decompositions exist.
