Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 564990, here are decompositions:

7 + 564983 = 564990
11 + 564979 = 564990
17 + 564973 = 564990
31 + 564959 = 564990
53 + 564937 = 564990
67 + 564923 = 564990
71 + 564919 = 564990
73 + 564917 = 564990

Showing the first eight; more decompositions exist.
