Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997582, here are decompositions:

29 + 997553 = 997582
41 + 997541 = 997582
71 + 997511 = 997582
149 + 997433 = 997582
191 + 997391 = 997582
239 + 997343 = 997582
263 + 997319 = 997582
419 + 997163 = 997582

Showing the first eight; more decompositions exist.
