Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997996, here are decompositions:

5 + 997991 = 997996
23 + 997973 = 997996
47 + 997949 = 997996
107 + 997889 = 997996
227 + 997769 = 997996
257 + 997739 = 997996
269 + 997727 = 997996
347 + 997649 = 997996

Showing the first eight; more decompositions exist.
