Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 577998, here are decompositions:

17 + 577981 = 577998
19 + 577979 = 577998
41 + 577957 = 577998
59 + 577939 = 577998
61 + 577937 = 577998
67 + 577931 = 577998
79 + 577919 = 577998
89 + 577909 = 577998

Showing the first eight; more decompositions exist.
