Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997648, here are decompositions:

11 + 997637 = 997648
59 + 997589 = 997648
101 + 997547 = 997648
107 + 997541 = 997648
137 + 997511 = 997648
257 + 997391 = 997648
269 + 997379 = 997648
389 + 997259 = 997648

Showing the first eight; more decompositions exist.
