Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997916, here are decompositions:

19 + 997897 = 997916
37 + 997879 = 997916
103 + 997813 = 997916
109 + 997807 = 997916
223 + 997693 = 997916
307 + 997609 = 997916
463 + 997453 = 997916
547 + 997369 = 997916

Showing the first eight; more decompositions exist.
