Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997816, here are decompositions:

3 + 997813 = 997816
5 + 997811 = 997816
23 + 997793 = 997816
47 + 997769 = 997816
89 + 997727 = 997816
167 + 997649 = 997816
179 + 997637 = 997816
227 + 997589 = 997816

Showing the first eight; more decompositions exist.
