Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997910, here are decompositions:

13 + 997897 = 997910
19 + 997891 = 997910
31 + 997879 = 997910
97 + 997813 = 997910
103 + 997807 = 997910
127 + 997783 = 997910
211 + 997699 = 997910
229 + 997681 = 997910

Showing the first eight; more decompositions exist.
