Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 564728, here are decompositions:

19 + 564709 = 564728
61 + 564667 = 564728
271 + 564457 = 564728
337 + 564391 = 564728
421 + 564307 = 564728
457 + 564271 = 564728
499 + 564229 = 564728
601 + 564127 = 564728

Showing the first eight; more decompositions exist.
