Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997564, here are decompositions:

11 + 997553 = 997564
17 + 997547 = 997564
23 + 997541 = 997564
53 + 997511 = 997564
101 + 997463 = 997564
131 + 997433 = 997564
137 + 997427 = 997564
173 + 997391 = 997564

Showing the first eight; more decompositions exist.
