Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581000, here are decompositions:

3 + 580997 = 581000
19 + 580981 = 581000
31 + 580969 = 581000
61 + 580939 = 581000
73 + 580927 = 581000
109 + 580891 = 581000
157 + 580843 = 581000
163 + 580837 = 581000

Showing the first eight; more decompositions exist.
