Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997950, here are decompositions:

17 + 997933 = 997950
53 + 997897 = 997950
59 + 997891 = 997950
61 + 997889 = 997950
71 + 997879 = 997950
73 + 997877 = 997950
137 + 997813 = 997950
139 + 997811 = 997950

Showing the first eight; more decompositions exist.
