Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997938, here are decompositions:

5 + 997933 = 997938
41 + 997897 = 997938
47 + 997891 = 997938
59 + 997879 = 997938
61 + 997877 = 997938
127 + 997811 = 997938
131 + 997807 = 997938
197 + 997741 = 997938

Showing the first eight; more decompositions exist.
