Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578000, here are decompositions:

19 + 577981 = 578000
43 + 577957 = 578000
61 + 577939 = 578000
103 + 577897 = 578000
127 + 577873 = 578000
151 + 577849 = 578000
193 + 577807 = 578000
373 + 577627 = 578000

Showing the first eight; more decompositions exist.
