Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997936, here are decompositions:

3 + 997933 = 997936
47 + 997889 = 997936
59 + 997877 = 997936
167 + 997769 = 997936
197 + 997739 = 997936
347 + 997589 = 997936
353 + 997583 = 997936
383 + 997553 = 997936

Showing the first eight; more decompositions exist.
