Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997732, here are decompositions:

5 + 997727 = 997732
83 + 997649 = 997732
149 + 997583 = 997732
179 + 997553 = 997732
191 + 997541 = 997732
269 + 997463 = 997732
293 + 997439 = 997732
353 + 997379 = 997732

Showing the first eight; more decompositions exist.
