Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997600, here are decompositions:

3 + 997597 = 997600
11 + 997589 = 997600
17 + 997583 = 997600
47 + 997553 = 997600
53 + 997547 = 997600
59 + 997541 = 997600
89 + 997511 = 997600
137 + 997463 = 997600

Showing the first eight; more decompositions exist.
