Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997956, here are decompositions:

7 + 997949 = 997956
23 + 997933 = 997956
59 + 997897 = 997956
67 + 997889 = 997956
79 + 997877 = 997956
149 + 997807 = 997956
163 + 997793 = 997956
173 + 997783 = 997956

Showing the first eight; more decompositions exist.
