Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565320, here are decompositions:

17 + 565303 = 565320
31 + 565289 = 565320
37 + 565283 = 565320
47 + 565273 = 565320
59 + 565261 = 565320
61 + 565259 = 565320
73 + 565247 = 565320
79 + 565241 = 565320

Showing the first eight; more decompositions exist.
