Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997954, here are decompositions:

5 + 997949 = 997954
227 + 997727 = 997954
317 + 997637 = 997954
401 + 997553 = 997954
443 + 997511 = 997954
491 + 997463 = 997954
521 + 997433 = 997954
563 + 997391 = 997954

Showing the first eight; more decompositions exist.
