Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997922, here are decompositions:

31 + 997891 = 997922
43 + 997879 = 997922
109 + 997813 = 997922
139 + 997783 = 997922
181 + 997741 = 997922
223 + 997699 = 997922
229 + 997693 = 997922
241 + 997681 = 997922

Showing the first eight; more decompositions exist.
