Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565942, here are decompositions:

5 + 565937 = 565942
23 + 565919 = 565942
53 + 565889 = 565942
149 + 565793 = 565942
173 + 565769 = 565942
281 + 565661 = 565942
353 + 565589 = 565942
359 + 565583 = 565942

Showing the first eight; more decompositions exist.
