Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997986, here are decompositions:

13 + 997973 = 997986
23 + 997963 = 997986
37 + 997949 = 997986
53 + 997933 = 997986
89 + 997897 = 997986
97 + 997889 = 997986
107 + 997879 = 997986
109 + 997877 = 997986

Showing the first eight; more decompositions exist.
