Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565580, here are decompositions:

13 + 565567 = 565580
31 + 565549 = 565580
61 + 565519 = 565580
73 + 565507 = 565580
97 + 565483 = 565580
139 + 565441 = 565580
151 + 565429 = 565580
193 + 565387 = 565580

Showing the first eight; more decompositions exist.
