Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997976, here are decompositions:

3 + 997973 = 997976
13 + 997963 = 997976
43 + 997933 = 997976
79 + 997897 = 997976
97 + 997879 = 997976
163 + 997813 = 997976
193 + 997783 = 997976
277 + 997699 = 997976

Showing the first eight; more decompositions exist.
