Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565272, here are decompositions:

11 + 565261 = 565272
13 + 565259 = 565272
31 + 565241 = 565272
83 + 565189 = 565272
89 + 565183 = 565272
101 + 565171 = 565272
109 + 565163 = 565272
163 + 565109 = 565272

Showing the first eight; more decompositions exist.
