Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997908, here are decompositions:

11 + 997897 = 997908
17 + 997891 = 997908
19 + 997889 = 997908
29 + 997879 = 997908
31 + 997877 = 997908
97 + 997811 = 997908
101 + 997807 = 997908
139 + 997769 = 997908

Showing the first eight; more decompositions exist.
