Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997944, here are decompositions:

11 + 997933 = 997944
47 + 997897 = 997944
53 + 997891 = 997944
67 + 997877 = 997944
131 + 997813 = 997944
137 + 997807 = 997944
151 + 997793 = 997944
193 + 997751 = 997944

Showing the first eight; more decompositions exist.
