Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997570, here are decompositions:

17 + 997553 = 997570
23 + 997547 = 997570
29 + 997541 = 997570
59 + 997511 = 997570
107 + 997463 = 997570
131 + 997439 = 997570
137 + 997433 = 997570
179 + 997391 = 997570

Showing the first eight; more decompositions exist.
