Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997584, here are decompositions:

11 + 997573 = 997584
31 + 997553 = 997584
37 + 997547 = 997584
43 + 997541 = 997584
73 + 997511 = 997584
131 + 997453 = 997584
151 + 997433 = 997584
157 + 997427 = 997584

Showing the first eight; more decompositions exist.
