Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565980, here are decompositions:

7 + 565973 = 565980
43 + 565937 = 565980
59 + 565921 = 565980
61 + 565919 = 565980
71 + 565909 = 565980
73 + 565907 = 565980
89 + 565891 = 565980
113 + 565867 = 565980

Showing the first eight; more decompositions exist.
