Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997566, here are decompositions:

13 + 997553 = 997566
19 + 997547 = 997566
103 + 997463 = 997566
113 + 997453 = 997566
127 + 997439 = 997566
139 + 997427 = 997566
197 + 997369 = 997566
223 + 997343 = 997566

Showing the first eight; more decompositions exist.
