Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581004, here are decompositions:

7 + 580997 = 581004
23 + 580981 = 581004
103 + 580901 = 581004
113 + 580891 = 581004
167 + 580837 = 581004
191 + 580813 = 581004
197 + 580807 = 581004
211 + 580793 = 581004

Showing the first eight; more decompositions exist.
