Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565722, here are decompositions:

61 + 565661 = 565722
71 + 565651 = 565722
109 + 565613 = 565722
139 + 565583 = 565722
151 + 565571 = 565722
163 + 565559 = 565722
173 + 565549 = 565722
211 + 565511 = 565722

Showing the first eight; more decompositions exist.
