Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997548, here are decompositions:

7 + 997541 = 997548
37 + 997511 = 997548
109 + 997439 = 997548
157 + 997391 = 997548
179 + 997369 = 997548
191 + 997357 = 997548
229 + 997319 = 997548
239 + 997309 = 997548

Showing the first eight; more decompositions exist.
