Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565220, here are decompositions:

13 + 565207 = 565220
31 + 565189 = 565220
37 + 565183 = 565220
43 + 565177 = 565220
109 + 565111 = 565220
151 + 565069 = 565220
163 + 565057 = 565220
181 + 565039 = 565220

Showing the first eight; more decompositions exist.
