Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581028, here are decompositions:

31 + 580997 = 581028
47 + 580981 = 581028
59 + 580969 = 581028
89 + 580939 = 581028
101 + 580927 = 581028
109 + 580919 = 581028
127 + 580901 = 581028
137 + 580891 = 581028

Showing the first eight; more decompositions exist.
